摘　　要：为探究还原氧化石墨烯(rGO)和聚吡咯(PPy)配合使用在电阻式应变传感材料制备中的应用,以锦纶针织物为基材,然后依次对其进行rGO和PPy改性处理。然后利用SEM照片、FT-IR光谱和XRD图谱对制备的PPy-rGO改性锦纶针织物进行表征。得益于PPy-rGO改性锦纶针织物的高导电性[(345±6)Ω/4 cm]和较好的延伸性,其所构建的应变传感器表现出较快反应(反应时间31 ms)和良好的循环稳定性(循环时间2 400 s)。此外,该应变传感器还能有效监测人体关节运动,为针织物应变传感材料的制备提供理论参考。The purpose of this paper is to explore the application potential of reduced graphene oxide(r GO)and polypyrrole(PPy)in the preparation of resistive strain sensing materials.The nylon knitted fabric was used as base material,and then modified by r GO and PPy in turn.Then SEM image,FT-IR spectra and XRD pattern were used to characterize the PPy-r GO modified nylon knitted fabric.Thanks to the high electrical conductivity(345±6)Ω/4 cm and good extensibility of PPy-r GO modified nylon knitted fabric,the strain sensor shows fast response(reaction time 31 ms)and good cycle stability(cycle time 2400 s).In addition,the strain sensor can effectively monitor the motion of human joints,which provides a theoretical reference for the preparation of knitted fabric strain sensing material.
