摘　　要：Fabric multifunctionality offers resource savings and enhanced human comfort.This study innovatively integrates cooling,heating,and antimicrobial properties within a Janus fabric,surpassing previous research focused solely on cooling or heating.Different effects are achieved by applying distinct coatings to each side of the fabric.One graphene oxide(GO)coating exhibits exceptional light-to-heat conversion,absorbing and transforming light energy into heat,thereby elevating fabric temperature by 15.4℃,22.7℃,and 43.7℃ under 0.2,0.5,and 1 sun irradiation,respectively.Conversely,a hydrogel coating on one side absorbs water,facilitating heat dissipation through evaporation upon light exposure,reducing fabric temperature by 5.9℃,8.4℃,and 7.1℃ in 0.2,0.5,and 1 sun irradiation,respectively.Moreover,both sides of Janus fabric exhibit potent antimicrobial properties,ensuring fabric hygiene.This work presents a feasible solution to address crucial challenges in fabric thermal regulation,providing a smart approach for intelligent adjustment of body comfort in both summer and winter.By integrating heating and cooling capabilities along with antimicrobial properties,this study promotes sustainable development in textile techniques.
