As a new type of zero-dimensional nanoluminescent material, carbon dots (CDs) have attracted extensive attention and in-depth research in recent years due to their rich and excellent luminescence properties. In this study, sodium-doped CDs (Na-CDs) were synthesized under three different sodium source conditions by hydrothermal method, and the regulation mechanism of Na-doped on the structure and optical properties of CDs was systematically studied by comparing with undoped control samples. The results show that Na-doped does not significantly change the particle size and crystal structure of CDs, but can significantly increase the proportion of graphite nitrogen (from 12.3 % to 65.3 %), enhance the order of sp2 carbon structure, thereby effectively inhibiting pi-pi stacking, and significantly improving the fluorescence quenching problem of CDs in the solid state. Among them, the self-doped CDs-1 exhibits strong and stable blue fluorescence in both solution and solid state, with emission peaks at 447 nm and 455 nm, respectively, phosphorescence quantum yields (PLQY) of 22.61 % and 9.02 %, respectively, and an average fluorescence lifetime of 7.75 ns, which is much higher than other samples. Temperature response experiments show that the fluorescence intensity of CDs-1 shows a decay trend with increasing temperature in the range of 80-300 K, and shows a good linear relationship in the range of 160-300 K. The fluorescence intensity decreases by an average of 0.0191 % for every increase of 1 K, showing excellent temperature sensitivity and stability. This study provides new ideas for the design of high-performance solid-state luminescent CDs and expands their application potential in the field of optical functional materials such as non-contact temperature sensing.

Efficient solid–liquid separation is essential for industrial effluent discharge compliance and for mitigating water scarcity and environmental pollution. Highly turbid wastewater containing fine kaolin is difficult to treat because small particle size and strong negative surface charge promote the formation of stable colloidal suspensions. This study aimed to develop a green and efficient lignin-based flocculant for the purification of highly stable colloidal systems. Inspired by the coordinated capture behaviour of multiple octopus tentacles, an interfacial enhancement–multi-arm bridging strategy was proposed. Xanthate groups were introduced into the lignin backbone to strengthen particle–polymer interfacial interactions, and cationic acrylamide–diallyldimethylammonium chloride segments were grafted via a ”grafting to” strategy to construct a biomimetic multi-arm xanthated lignin-based flocculant. The optimised flocculant exhibited excellent turbidity removal performance at low dosages, achieving 99.72% turbidity removal at only 2.5 mg/L under optimal conditions, while maintaining high treatment efficiency over a broad pH range of 3–11. This work provides a feasible strategy for designing high-performance bio-based flocculants for treating highly stable colloidal systems.

Solid-state ion-conductive elastomers are promising materials for self-powered flexible electronics, yet simultaneously achieving mechanical robustness, efficient ion transport, environmental durability, and recyclability remains challenging. Herein, a polyurethane-based solid-state ion-conductive elastomer was developed through rational soft and hard segment design combined with multiple dynamic interactions. Hydrogen bonding, π–π stacking, dynamic acylhydrazone bonds, and Li⁺ coordination collectively form a three-dimensional dynamic network composed of reversible noncovalent interactions and dynamic covalent crosslinks, enabling an effective balance between segmental mobility and network stability. The optimized ADPU-100Li exhibits a tensile strength of 7.26 MPa and an ionic conductivity of 4.11 × 10-4 S cm-1, while maintaining stable mechanical and ion-transport properties over a wide temperature range and after exposure to various organic solvents. In addition, the dynamic network enables effective recovery and reuse of the elastomer, while LiTFSI can be separated through a solvent-based process and reused to reconstruct ion-conductive elastomers with well-preserved functional performance. As a proof of application, an ADPU-100Li-based contact-separation triboelectric nanogenerator delivers an open-circuit voltage of 100 V, a short-circuit current of 15 μA, a transferred charge of 33 nC, and a maximum power density of 4.0 W m⁻², with stable output during prolonged cycling. Combined with a convolutional neural network, the self-powered system achieves classification accuracies above 97% for material and surface-roughness recognition. These results establish a structure, property and recyclability relationship for polyurethane-based solid-state ion-conductive elastomers and provide a viable strategy for developing durable, recyclable, and multifunctional ionic materials for self-powered sensing.

With the growing applications of carbon dots (CDs) in optical functional materials, the development of roomtemperature phosphorescent (RTP) CDs has become a significant research direction. However, most studies have focused on ultraviolet light excitation for RTP, with little attention given to CDs excited by sunlight. This study presents, for the first time, a sunlight-excited time-dependent RTP CDs composite, N-CDs@Al2O3, synthesized via a one-step hydrothermal-assisted calcination method using biomass-derived sucrose. Nitrogen-doped CDs were in situ embedded in a rigid Al2O3 matrix, resulting in an ultralong RTP lifetime (1.22 s, visible up to 30 s) and a time-dependent phosphorescence color (TDPC) shift from orange to green. The composite exhibits a high photoluminescence quantum yield (PLQY) of 58.36 %. The observed RTP characteristics arise from the synergy between nitrogen doping, matrix rigidity, and oxygen vacancy control. This green material not only shows excellent stability but also holds promising applications in anti-counterfeiting, fingerprint imaging, and traffic signage.

With the development of flexible electronics and wearable sensing technologies, conductive materials are increasingly required to withstand complex deformations while maintaining stable signal output. Solid-state ion-conductive elastomers are attractive for flexible sensing because they avoid liquid leakage and water loss, yet balancing mechanical stability with ion transport remains challenging. Here, a multiply crosslinked polyurethane network containing lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) was developed as a high-performance solid-state ion-conductive elastomer. Reversible hydrogen bonds and dynamic acylhydrazone bonds promoted energy dissipation and network rearrangement, while permanent covalent crosslinks preserved structural integrity. LiTFSI further regulated polymer-chain interactions and phase structure, enabling the synergistic optimization of mechanical performance and ion transport. The optimized elastomer exhibited a tensile strength of 8.75 MPa and a room-temperature ionic conductivity of 3.13 × 10−4 S cm−1, together with stable electrical responses under large deformation, cyclic loading, and localized damage. The resulting strain sensor enabled Morse-code information encoding and five-channel digital gesture recognition with an accuracy above 98%. In addition, LiTFSI was recovered from discarded elastomers and reused for two cycles, and the regenerated materials retained performance comparable to that of the original material. This work provides a promising strategy for developing solid-state ion-conductive elastomers and expands their potential applications in intelligent wearable sensing.

Per- and polyfluoroalkyl substances (PFAS) represent a critical class of persistent environmental pollutants that challenge conventional remediation technologies. Metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and the emerging metal-covalent organic frameworks (MCOFs) have attracted growing interest as tunable porous platforms for removing per- and polyfluoroalkyl substances (PFAS) from water. This review critically summarizes recent advances in the synthesis, structural characterization, and adsorptive performance of these three framework families. We examine key factors affecting adsorption, including solution chemistry and PFAS chain length, and elucidate the underlying mechanisms-hydrophobic/fluorophilic interactions, electrostatics, anion exchange, and coordination-through combined experimental and computational evidence. A comparative assessment evaluates adsorption capacities, kinetics, stability, and regenerability, identifying the distinctive advantages of each material class. Practical applications in fixed-bed columns and magnetic composites are also discussed. Finally, we highlight persistent challenges, particularly in the removal of ultrashort-chain PFAS, and outline future directions involving machine learning, defect engineering, and dual-functional adsorptive-catalytic platforms to guide rational adsorbent design.

Solid-state ion-conductive elastomers (SICEs) as novel conductive elastomer materials are the most attractive candidates for energy-harvesting devices. However, integrating mechanical properties, conductivity, and harsh environment resistance into SICEs remains a significant challenge. Here, we propose a "three birds with one stone" strategy based on the fluorine effect to prepare a fluorinated SICE (TICE-70Li) with excellent mechanical performance, conductivity, and environmental stability. Benefiting from multiple interactions and fluorination effects, TICE-70Li exhibits outstanding mechanical performance (7.35 MPa and 61.4 MJ m-3) and ionic conductivity (4.2 x 10-4 S cm-1). Compared with fluorine-free SICE (DICE-XLi), the comprehensive performance of TICE-70Li has been fully improved. Moreover, TICE-70Li exhibits excellent resilience, environmental stability, and self-healing performance. The triboelectric nanogenerators (TICE-TENG) based on TICE-70Li not only demonstrate high power density (1.72 W m-2), but also can be stably operated in a variety of harsh environments. TICE-TENG based paper-folding TENGs enable energy harvesting for a wide range of water wave motions. Notably, we achieve the recycling and reutilization of polyurethane elastomers and LiTFSI by solvent recycling. This work provides new strategies for the construction of high-performance fluorinated SICEs and environmentally stable energy-harvesting devices, providing new insight into the sustainability of SICEs.

Ionic gel materials, with their excellent flexibility, show great potential for use in wearable electronics, ion skin, and soft robotics. However, due to the inherent contradictions within gel materials, balancing their mechanical and electrical properties is a major challenge. Inspired by the structure of shark skin, we adopted a strategy combining non-dynamic covalent interactions with dynamic covalent cross-linking. By introducing isophthaloyl hydrazine and 2,2-bis(trifluoromethyl)diaminobiphenyl as chain extenders and an innovatively synthesized polyhydroxy crosslinking agent (TABA) into the polymer network, we successfully prepared a novel dynamically crosslinked polyurethane-based ionic gel. It exhibits outstanding performance, including high strength (8.78 MPa), high toughness (81.37 MJ/m3 ), high ionic conductivity (1.24 x 10-4 S/cm), excellent stability, remarkable self-healing ability (self-healing efficiency of 96.92%), and recyclability. Additionally, due to the dynamic cross-linked structure in the molecular network, the gel material exhibits high fracture energy, crack insensitivity, and puncture resistance. We further mimicked the ampullary canal structure of sharks to fabricate an ionic gel sensor with a micro-needle structure, which (0-0.6%, GF = 135.55) demonstrates strong electro-sensing capabilities similar to those of sharks. Due to the presence of fluorine in the polyurethane matrix and the hydrophobic nature of ionic liquids (IL), the ionic gel also exhibits outstanding hydrophobicity, enabling innovative applications in underwater communication and underwater biological movement monitoring. Furthermore, we pioneered the use of solvent extraction to achieve the recovery of IL, actively responding to the call for environmental sustainability.

Regional lymph node (LN) dissection is often used for the treatment of deep LNs in tumour surgery; however, the method is prone to incomplete LN dissection, trauma, complications, and other side effects. LN tracers make it easier to visualise and remove LNs. However, the current common LN tracers only have a single function or have radiation hazards related to their use. Therefore, the use of multi-functional LN tracers to improve the efficiency of deep LN eradication and reduce trauma and complications is currently a major challenge to be addressed. This study aimed to develop a multi-functional citrate-coated magnetite nanoparticle (CMNP) that could specifically drain to and accumulate in LNs. The CMNPs can be used as photoacoustic imaging contrast agents and magnetic resonance imaging contrast agents to image LNs. When an alternating magnetic field is applied, the CMNP can generate heat and raise the temperature of LNs, which is sufficient to coagulate and necrotise the LNs, thereby achieving LN inactivation. Eradication of LNs by magnetic hyperthermia is not limited by depth, and only LNs are specifically heated. Moreover, the method is less invasive and accurate for deep LNs.

Wood adhesives that combine high bonding strength with electromagnetic interference shielding capabilities have attracted widespread attention. Inspired by the organic-inorganic hybrid structures found in organisms such as oysters, this study designed and constructed a nanophase-reinforced organic-inorganic hybrid cross-linked network. The system, based on the synergistic interaction of carboxylated styrene-butadiene latex adhesive, sodium alginate (SA), and carbon nanotubes (CNTs), significantly enhanced the bonding strength of the adhesive and endowed it with electromagnetic interference (EMI) shielding performance. SA was incorporated into the XSBL matrix, and tetraethylenepentamine was used to induce amide cross-linking, forming a stable covalently cross-linked network. Meanwhile, the physical incorporation of CNTs formed conductive pathways within the matrix, thereby improving the electrical conductivity and EMI shielding effectiveness of the material. When the CNTs content reached 15 wt%, the resulting adhesive exhibited a dry bonding strength of 4.48 MPa, an increase of 348 % compared to the original XSBL, and achieved a high electrical conductivity of 15.18 S/m. The corresponding three-layer plywood demonstrated an EMI shielding effectiveness of up to 32 dB. This study provides a feasible adhesive design strategy for high-performance, multifunctional wood-based plywood intended for use in electronic environments, offering new insights into the development of functional wood materials.

Leaks during oil extraction, wastewater containing organic solvents from industrial production and oily wastewater from daily life pose a great threat to the ecosystem and human life, which makes the research and development of oil-water separation materials imminent. Nanocellulose aerogels possess lightweight properties, high porosities, and excellent adsorption capabilities, making them efficient adsorbents for the removal of oil spills and organic pollutants. A novel method is presented utilizing the self-polymerization characteristics of polydopamine (PDA) to encapsulate titanium dioxide (TiO2) nanoparticles, thereby forming core-shell nano- particles. The unique adhesive properties of PDA play a critical role in the binding of these nanoparticles to a cellulose nanofiber (CNF) scaffold, resulting in a robust composite material. To further enhance the performance of the aerogel, octadecyltrimethoxysilane (OTMS) was incorporated, imparting hydrophobicity to the overall structure, resulting in the OTMS/TiO2@PDA/CNF aerogel. This aerogel exhibited outstanding adsorption capabilities and absorbed various light and heavy oils, as well as organic solvents, with an adsorption capacity of up to 59.9 g/g. Under gravity, the separation efficiency of the aerogel reached 96.15 %. An innovative oil collection device was designed for the sustainable separation of pollutants from water to ensure efficient cleanup operations. Furthermore, the aerogel exhibited excellent antibacterial properties with a bactericidal rate of up to 99.14 % and significantly enhanced environmental adaptability. This simple, economical, and environment- friendly method is expected to promote the development of efficient oil/water separation adsorbents and contribute to the control of environmental pollution.

Isocyanate is a highly reactive compound that quickly reacts with active hydrogen, posing challenges in its use in emulsion adhesives. Micro/nanoencapsulation technology involves enclosing a core material with a protective shell under specific conditions. Encapsulating isocyanate via micro/nanoencapsulation extends its lifespan in emulsion adhesives and enables controlled release, improving the mechanical strength of the adhesive. In this study, polyurea was used as the shell material and isophorone diisocyanate as the core to prepare isocyanate micro/nanofillers via micro/nanoencapsulation. Isocyanate micro/nanofillers were prepared through interfacial polymerization in an oil-in-water system with process optimization. The obtained isocyanate micro/nanofillers had an active group content of 22.1wt %. The shielding effect of the shell effectively prolonged the lifespan of isocyanate groups in the emulsion. After six weeks of storage, the isocyanate micro/nanofillers retained most of their activity, showing satisfactory stability. When used as functional cross-linking agents in emulsion adhesives, pressure-induced rupture of the isocyanate micro/nanofillers triggered reactions with compounds containing active hydrogen, forming strong chemical bonds and significantly improving lap shear strength (4.01MPa), which is 4.22 times that of the original latex. Transforming isocyanate from liquid to solid via micro/nanoencapsulation not only extended its lifespan but also improved bonding performance. The prepared adhesive was solvent-free, energy-efficient, environmentally friendly, clean, low-cost, and offered excellent bonding strength. These findings will enable broad practical applications in wood structural joints, engineering assemblies, and related fields.

Nucleus labeling is significant to dynamic monitor many physiological and pathophysiological processes. In the current work, a nuclear-targeted carbon dots (named as mf-CDs) was synthesized from m-phenylenediamine and folic acid through the hydrothermal method. The prepared mf-CDs were water-soluble and could specifically "light up" the nucleus whether it's normal cells or cancer cells. Remarkably, this staining process is both ultrafast and wash-free. The universality of mf-CDs was demonstrated through successful imaging across diverse cell systems. Including bacterial species such as Escherichia coli and Nitrogen fixing bacteria, fungi like Rhizoctonia solani and Saccharomyces cerevisiae, as well as plant cells from onion epidermis. Notably, excellent nuclear specificity was observed in Saccharomyces cerevisiae and onion epidermal cells. More interestingly, the Escherichia coli or Saccharomyces cerevisiae preloaded with low concentration (3.0 μg/mL) of mf-CDs effectively stained live HepG2 cells, high-resolution images fluorescence image was obtained within 4 min. Revealing that mf-CDs could ultrafast label the living cells under extremely low concentration conditions. To the best of our knowledge, this novel bacteria-mediated staining process has not been previously reported. The current work advances ultralow-concentration CDs bioimaging and pioneers microbial-mediated cellular analysis, offering new tools to study nanoparticle-cell interactions.

Solid-state ion-conductive elastomers (ICEs) serve as core materials for flexible electronic devices, demonstrating significant application potential in flexible pressure sensing, wearable electronics, and soft robotics. However, achieving a synergistic enhancement of mechanical properties and ionic conductivity in solid-state ion-conductive elastomers remains a substantial challenge. In this study, a multiple cross-linking strategy was employed. By incorporating lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) into a polyurethane matrix, a polyurethane-based solid-state ion-conductive elastomer (designated MCPU-100Li) exhibiting concurrent high mechanical strength and high ionic conductivity was designed and synthesized. Benefiting from the multiple cross-linked network within the polymer, MCPU-100Li demonstrates high tensile strength (6.56 MPa), high ionic conductivity (5.84 x 10-4 S cm-1), high tear resistance with a fracture energy of 17.4 kJ m-2 and good environmental stability. The flexible pressure sensor based on MCPU-100Li exhibits high sensitivity, rapid response, and robust stability, enabling precise detection of electrical signal variations under different pressures. Furthermore, integrated with a chessboard-like array, this sensor achieves high-resolution spatial mapping of position and pressure through multichannel signal analysis, demonstrating capabilities for diverse board layouts and dynamic recognition. Additionally, MCPU-100Li functions effectively as a key triboelectric layer material in triboelectric nanogenerators (TENGs), highlighting its promising potential for applications in wearable electronics and energy harvesting.

Thermoelectric generators (TEGs) are capable of converting part of the unreusable light and heat energy into electrical energy, which is an emerging energy harvesting technology. However, the photothermal conversion layer, as a key component of the TEG, is susceptible to mechanical damage and structural damage under the influence of external stress stimuli and high-temperature environments, which affects the stable operation of the TEG. Therefore, it is a great challenge to develop a photothermal conversion layer that combines excellent mechanical properties and thermal stability. This study develops a multistep cross-linking strategy to prepare high-performance elastomers. The composite contains a carboxylated nitrile rubber (XNBR) matrix, hydroxyethyl methacrylate (HEMA) grafts, and dual ZnO nanofillers and carbon black. The fabrication process sequentially integrates grafting, hydrogenation, filler incorporation, and cross-linking. The optimized material demonstrates enhanced mechanical properties with a tensile strength of 8.1 MPa. Its thermal stability is improved, showing an initial decomposition temperature at 393 °C. Subsequently, a rubber-based thermoelectric generator (R-TEG) was assembled, and the R-TEG showed excellent output performance and stability and was able to stably output a voltage of 1.2 V when irradiated with a near-infrared lamp for 400 s; the corresponding power density is 18.375 μW/cm2. This study provides a strategy for developing TEGs with strong output performance and stable operation, thus contributing to sustainable energy solutions.

The realization of multicolor luminescence under varied excitation conditions through doping multiple metal ions into lead-free double perovskites (DPs) holds significant research value. However, conventional crystalline powder materials currently exhibit limitations in synthesis flexibility and practical application. This study proposes an in situ fabrication strategy using dimethyl sulfoxide (DMSO) as a solvent to achieve low-temperature growth of Cs2NaIn0.Sb-8(0).Cl-2(6) DPs within poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), while incorporating Tb3+ and Mn2+ ions to obtain DPs@PVDF-HFP composite films (CFs) with distinct luminescent properties. By modulating the doping concentrations of Tb3+ and Mn2+, effective control over the luminescence color of the CFs was achieved. Results indicate that Tb3+ doping introduces narrow-band green emission, whereas Mn2+ doping activates orange-red emission. Multicolor-tunable luminescence was realized by adjusting dopant concentrations and excitation wavelengths (254-365 nm). Co-doping of Tb3+ and Mn2+ into Cs2NaIn0.Sb-8(0).Cl-2(6)@PVDF-HFP revealed an efficient energy transfer mechanism from Sb3+ self-trapped excitons (STEs) to Tb3+/Mn2+ via temperature-dependent photoluminescence (PL) spectroscopy. The optimized CFs (Cs2NaIn0.Sb-8(0).Cl-2(6):0.090 Tb3+,0.0060Mn(2+)@PVDF-HFP) demonstrated exceptional thermal stability, photostability, and moderate water resistance, retaining over 82 % of initial luminescence intensity after 30 h of heating at 100 degrees C or continuous 365 nm UV irradiation. Leveraging these advantages, multicolor LED devices were successfully fabricated, showcasing application potential in intelligent displays and security anti-counterfeiting. The tunable multicolor emission of the CFs further validates the prospects of co-doped double perovskites in anti-counterfeiting technologies and multicolor illumination systems.

Wood‐based composite materials exhibit significant potential for applications in complex environments such as polar house construction and offshore oil engineering. Excellent wood adhesives are crucial for the weather resistance, structural toughness, and environmental performance of wooden products. However, traditional adhesives suffer from poor water resistance, toxic residue, and reliance on high‐temperature press curing. Inspired by the crosslinking of bird nest proteins, this study modifies carboxylated styrene‐butadiene latex through in situ epoxidation, converting non‐polar double bonds into highly reactive groups. By combining multi‐amino prepolymers, modified silica, and epoxy‐modified emulsion, a dual physical‐chemical crosslinking system is constructed, resulting in the development of a cold‐press adhesive. The material demonstrates excellent dry/wet shear strength (4.03/1.96 MPa) and debonding work (2.47 J), with a minimal strength loss of less than 7% across extreme temperature ranges (−196 to 85 °C) and significantly improved low‐temperature brittleness (−196 °C strength retention at 3.67 MPa). Additionally, it exhibits long‐lasting solvent resistance (70% strength retention after 36 days of immersion) as well as flame‐retardant properties. Based on these excellent properties, wood adhesives designed for heat‐free bonding are expected to be used in a variety of complex environments, including polar house construction, deep‐sea oil extraction, and space applications.

Carbon dots (CDs) have attracted considerable interest as fluorescent nanomaterials; however, their long-afterglow emission properties remain underexplored. In this study, we synthesized dual-mode afterglow CDs exhibiting room-temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) via fluorine-sodium (F, Na) co-doping, achieving an extended afterglow lifetime of 574 ms. Under 365 nm UV excitation, the afterglow emission persists for 14 s (naked-eye observation) and 40 s (instrumentally quantified), demonstrating exceptional temporal resolution. Na doping enhances afterglow intensity by 11.3 %, while fluorine doping reduces the singlet-triplet energy gap (ΔEST) to 0.036 eV, facilitating efficient Reverse Intersystem Crossing and enabling TADF behavior. These synergistic effects position the developed CDs as promising candidates for anti-counterfeiting systems, multilevel data encryption, and high-security optical tagging.

Conductive adhesives offer considerable promise in areas such as disaster warning and structural bonding in timber buildings. However, current conductive adhesives suffer from low bonding strength, poor interfacial adhesion, low cohesive strength, and low sensitivity. Conventional wood adhesives consume considerable energy due to their reliance on hot pressing. Here, this work introduced a styrene-butadiene rubber-based conductive wood adhesive with high environmental sensitivity, developed using interfacial polarity modification and functional filler doping. This conductive adhesive exhibited exceptionally high cold-press lap shear strength (dry shear strength of 3.67 MPa and wet shear strength of 1.80 MPa), strong interfacial adhesion (rapid bonding to polar, nonpolar, and inorganic surfaces), high conductivity (adhesive film conductivity of 0.13 S m-1), and outstanding cohesive strength (5.28 MPa). Exploiting these superior properties, a multilayered (wood-adhesive-wood) environment-sensitive sensor can rapidly identify various early disaster signals, including vibration, temperature rise, and combustion. This study introduced strategies for developing low-energy, high-strength conductive adhesives for timber buildings, thus opening innovative avenues for early disaster warning in timber buildings.

Wood adhesives are extensively utilized in furniture manufacturing and repair as well as in the construction industry. Developing adhesives that possess rapid bonding capabilities, exceptional adhesive strength, and the ability to cure without heating is a significant area of research. During application, plywood often experiences adhesive failure due to the stress concentration. Inspired by the structure of spider webs, this study developed a carboxylated styrene-butadiene latex-based wood adhesive capable of effectively dissipating stress while exhibiting superior adhesive strength. The strategy involves grafting trifluoroethyl acrylate and glycidyl methacrylate onto the carboxylated styrene-butadiene latex backbone, employing tetraethylenepentamine as a cross-linking agent to construct a multilevel cross-linked structure via ring-opening and amidation reactions. Motivated by the spider web structure, the adhesive forms a multilevel cross-linked network through covalent interactions such as amine ether and amide bonds between the main chains, enhancing the system's cohesion. Additionally, noncovalent interactions such as hydrogen bonds and pi-pi stacking improve interfacial adhesion and stress dissipation. These multiple interactions significantly enhance the adhesive strength. The adhesive can achieve rapid bonding within 3 min at room temperature, with a dry bonding strength of 3.29 MPa and a wet bonding strength of 1.91 MPa. The bonding process does not require additional heat sources, effectively reducing the energy consumption. Compared with traditional heat-curing adhesives, this adhesive offers low energy consumption, ease of operation, and environmental friendliness, making it highly suitable for applications in furniture maintenance and other scenarios where heat curing is impractical.
