摘　　要：Multifunctional wearable e-textiles have been a focus of much attention due to their great potential for healthcare,sportswear,fitness,space,and military applications.Among them,electroconductive textile yarn shows great promise for use as the next-generation flexible sensors without compromising properties and comfort of usual textiles.Recently,a myriad of efforts have been devoted to improving performance and functionality of wearable sensors.However,the current manufacturing process of metal-based electroconductive textile yarn is expensive,unscalable,and environmentally unfriendly.In this work,we report the preparation of multifunctional reduced graphene oxide/linen(RGO/LN)fabrics through the reduction and the followed suction filtration.Asprepared RGO/LN fabric could serve as the methane gas sensor,which exhibited high sensitivity,remarkable reliability and feasibility.Furthermore,the RGO/LN fabric sensor exhibited good moisture permeability and air permeability.The present work reveals that RGO/LN fabric has great potential as wearable smart devices in personal healthcare applications.
