摘　　要：基于导电聚合物的柔性电化学驱动器具有驱动电压低,成本低和环境适应性强等特点,在柔性驱动领域具有重要的研究意义。分别以硫酸和植酸作为掺杂剂合成导电聚苯胺,借助扫描电子显微镜和X射线衍射仪等表征方法,研究了掺杂剂对聚苯胺微观结构的影响。将掺杂态的导电聚苯胺作为添加剂加入到PEDOT∶PSS驱动器电极中,获得了一种具有高拉伸和高导电性(925S/cm)的电极,并且驱动器的最大质量电容可达到1F/g,最大弯曲位移为5.6mm。结果表明:聚苯胺作为添加剂对驱动器的驱动性能有较大的提升作用,为后续的研究提供了有益的借鉴意义。Flexible electrochemical actuators based on conductive polymers have the characteristics of low drive voltage,low cost and strong environmental adaptability,which have important research significance in the field of flexible driving.Conductive polyaniline was synthesized by using sulfuric acid and phytic acid as dopants,respectively.The effect of dopants on the microstructure of polyaniline was studied by means of scanning electron microscopy and X-ray diffraction.An electrode with high tensile and high conductivity(925S/cm)was obtained by adding doped conductive polyaniline as an additive to the PEDOT∶PSS actuator electrode.The maximum mass capacitance of the actuator could reach 1F/g and the maximum bending displacement was 5.6mm.The results showed that polyaniline,as an additive,could greatly improve the driving performance of the actuator,which provided a useful reference for the subsequent research.
