摘　　要：自行开发了电化学原位膜导电性测量仪(ECC).该测量仪将电化学的电位控制方法与电导率的测量有机地结合在一起,同时辅以双带及阵列探针电极,可在电化学电位调制下测定原位聚合物膜导电性的变化,特别是可以进行高时间分辨的动力学测量.以此为基础,测定了对电化学电位调制下导电聚合物膜导电性能,研究了电化学聚合的聚苯胺膜在一系列不同电位老化条件下的反应动力学.Conductivity of electrodeposited polyaniline was measured in-situ during the potential running, which is achieved at a homemade in-situ electrochemistry conductometer （ECC） integrated with a two-band electrode. The electrochemical response and change in resistance were recorded spontaneously. Furthermore, the first order reaction kinetics at various potentials was examined on basis of the changes of resistance, and the aging process of PANI film in the acid solution was also explored.
