摘　　要：运用循环伏安(CV)法制取聚苯胺,结合扫描电子显微镜(SEM)、阻抗谱(EIS)等手段,对聚苯胺的表面形貌及其特征进行研究,并建立了聚苯胺覆盖Pt电极的阻抗模型.实验表明,随着循环次数的增加,聚苯胺膜厚增加,而且所制得的聚苯胺膜呈现多孔、疏松的特征,符合其作为基体材料的特点.Using the methods of cyclic voltammetry （CV）, scanning electron microscopy （SEM）, electrochemical impedance spectroscopy （EIS）, the morphology and characteristics of polyaniline films were studied, and the equivalent circuit model of pure polyaniline film was established. The experimental results show that with the increase of cyclic numbers, the film thickness increases. Moreover, the polyaniline film shows porous and loose structure, so it can be used as support.
