首先制备了银纳米粒子(Ag NPs)搭载的氧化石墨烯(GO)分子膜；接着,将之均匀分散在商业Nafion 溶液中,得高储水、导电的 GO/Ag 杂化离子交换膜；然后,在膜两侧沉积 Pt 纳米电极,最终获得杂化的离子交换聚合物-金属复合材料(IPMC)电致动器。 IPMC 的交流阻抗谱(EIS)和电致响应测试结果表明, GO/Ag 掺杂后,离子交换膜的电导率增加,IPMC 的偏转角和力输出随着增加；IPMC 的电致动性能与离子交换膜的电导率紧密相关,电导率可作为评价IPMC 电致响应性能优劣的有价值参数。

In this paper,we firstly prepared graphene monolayer carrying Ag nano particles (GO/Ag NPs);then,widely dispersed GO/Ag NPs into the commercial the Nafion solution,thus obtained the GO/Ag NPs hy-brid ion-exchange membrane;finally,sandwiched the ion-exchange membrane by two layers of Pt nanosheets, thus obtained hybrid ion-exchange polymer metal composite (IPMC)actuator.Detections of electrochemical im-pedance spectroscopy (EIS)and electromechanical properties of IPMC show that,after hybrid of GO/Ag NPs, conductivity of the ion-exchange membrane increases,both the swing angle and force output increase;electro-mechanical property of IPMC has a close relationship with the conductivity,which can act as a valuable parame-ter to evaluate the electromechanical properties.
