摘　　要：Given the abundant solar light available on our planet,it is promising to develop an advanced fabric capable of simultaneously providing personal thermal management and facilitating clean water production in an energy-efficient manner.In this study,we present the fabrication of a photothermally active,biodegradable composite cloth composed of titanium carbide MXene and cellulose,achieved through an electrospinning method.This composite cloth exhibits favorable attributes,including chemical stability,mechanical performance,structural flexibility,and wettability.Notably,our 0.1-mm-thick composite cloth(RC/MXene IV)raises the temperature of simulated skin by 5.6℃when compared to a commercially available cotton cloth,which is five times thicker under identical ambient conditions.Remarkably,the composite cloth(RC/MXene V)demonstrates heightened solar light capture efficiency(87.7%)when in a wet state instead of a dry state.Consequently,this cloth functions exceptionally well as a high-performance steam generator,boasting a superior water evaporation rate of 1.34 kg m^(-2)h^(-1)under one-sun irradiation(equivalent to 1000 W m^(-2)).Moreover,it maintains its performance excellence in solar desali-nation processes.The multifunctionality of these cloths opens doors to a diverse array of outdoor applications,including solar-driven water evaporation and personal heating,thereby enriching the scope of integrated functionalities for textiles.
