摘　　要：Wearable gas sensors can improve early warning provision for workers in special worksites and can also be used as flexible electronic platforms.Here,the flexible multifunctional gas sensor was prepared by grafting graphene oxide(GO)-Ag onto cotton fabric after swelling.The maximum bacterial inhibition rate of GO-150/cotton fabric was 95.6%for E.coli and 87.6%for S.aureus,while retaining the original high moisture permeability of cotton fabric.So GO/cotton fabric can resist the multiplication of bacteria.At the same time,GO can greatly improve the UV protection performance of cotton fabric used in garments.With increase of the GO concentration,the UV protection ability of composite fabric is enhanced.Finally,GO-Ag/cotton fabric sensors had stable NH3 gassensitive properties and good washing stability.In conclusion,these cotton fabric sensors with antibacterial properties,UV resistance and highly sensitive gas-sensitive properties have potential applications in wearable early warning devices and textile products.
