Personal Microenvironment Management by Smart Textiles with Negative Oxygen Ions Releasing and Radiative Cooling Performance

In recent years, significant strides have been made inthe developmentof smart clothing, which combines traditional apparel with advancedtechnology. As our climate and environment undergo continuous changes,it has become critically important to invent and refine sophisticatedtextiles that enhance thermal comfort and human health. In this study,we present a "wearable forest-like textile". This textileis based on helical lignocellulose-tourmaline composite fibers,boasting mechanical strength that outperforms that of cellulose-basedand natural macrofibers. This wearable microenvironment does morethan generate approximately 18625 ions/cm(3) of negativeoxygen ions; it also effectively purifies particulate matter. Furthermore,our experiments demonstrate that the negative oxygen ion environmentcan slow fruit decay by neutralizing free radicals, suggesting promisingimplications for aging retardation. In addition, this wearable microenvironmentreflects solar irradiation and selectively transmits human body thermalradiation, enabling effective radiative cooling of approximately 8.2 & DEG;C compared with conventional textiles. This sustainable andefficient wearable microenvironment provides a compelling textilechoice that can enhance personal heat management and human health.
