摘　　要：采用化学还原法制备还原氧化石墨烯(RGO)-尼龙织物,并用场发射扫描电镜和拉曼光谱测试仪对其形貌和结构进行表征,用四探针表面电阻测试仪和电化学工作站测试RGO-尼龙织物的导电及传感性能。结果表明,经过6次浸渍-还原的RGO-尼龙织物导电性较好。RGO-尼龙织物的电阻随着应变的增大而增大,当应变减小时,电阻有恢复的趋势。恒压0.5 V时,电流信号可以很好地反映手指和手腕关节的运动,表明RGO-尼龙织物有望用作柔性应变传感器。Reduced graphene oxide(RGO)-nylon fabric was prepared via in-situ chemical reduction.The morphologies and structures were characterized by field emission scanning electron microscopy(FE-SEM)and Raman spectroscopy.The conductivity and strain sensing performances of RGO-nylon fabric were tested by four-probes and electrochemical workstation.The results showed that the RGO-nylon fabric by six times dipping-reduction had good conductivity.The resistance of RGO-nylon fabric increased with strain rising and had a recovery trend when the strain reduced.The current signal could reflect the joint movement of finger and wrist at constant voltage of 0.5 V,which indicated that RGO-nylon fabric could serve as a promising flexi⁃ble strain sensor.
