Scalable production of bioinspired MXene/black phosphorene nanocoatings for hydrophobic and fire-safe textiles with tunable electromagnetic interference and exceeding thermal management

Multifunctional fire-safe textiles are urgently needed to meet the application requirements under harsh envi-ronments, e.g., high-frequency environments. However, it is rather tough to realize scalable production of multifunctional fire-safe textiles by constructing coatings. To tackle the hurdles above, multifunctional fire-safe cotton fabric was prepared though a blade-coating strategy (using black phosphorus and Ti3C2Tx nano-dispersion ink), followed by hydrophobic treatment with poly (dimethylsiloxane) coating. The resultant textiles with the coating of micra-like structure exhibit excellent water resistance with a water contact angle of up to 93 degrees and excellent heat response within 10 s to the original temperature. Furthermore, the as-designed textiles demon-strate high flame retardancy and superior shielding effectiveness (SE) of 58 dB, which is much better than the reported treated fabric. The final treated fabric with high electromagnetic interference shielding effectiveness is suitable for most commercial applications. This work provides a promising strategy to produce functional textiles with superior electromagnetic interference and exceeding thermal management at a large scale, showing po-tential applications in electronic, electrical, and military fields.
