摘　　要：以聚酰亚胺（PI）膜为基体，采用分散聚合原位沉积方法制得聚苯胺／聚酰亚胺／聚苯胺（PANI／PI／PANI）三层复合膜。复合膜表面PANI层外观质量优异，电导率达10^0S／cm。实验结果表明：加入高浓度空间稳定剂（聚乙烯吡咯烷酮，PVP）、调整氧化剂（过硫酸铵，APS）和介质酸（盐酸）的用量可制得表面质量和电导率高的复合膜。较适宜的反应条件为稳定剂质量浓度4％，APS与苯胺（An）的物质的量比为2：4，盐酸浓度为0．5mol／L。Polyaniline/polyamide/polyaniline （PANI/PI/PANI） compound films were prepared through an in-situ deposition method on PI matrix in a dispersion polymerization system. The PANI layer of compound film had a high conductivity （10^0 S/cm） and an excellent appearance quality. In reaction system,the compound film was improved by adding high concentration of stabilizer（polyvinylpyrrolidone,PVP） ,and controlling a mount of oxidant and acid contribute. The typical reaction conditions were as follews ：concentration of PVP was 4 % ,ratio of ammonium persulfate and aniline was 2：4 and HC1 concentration was 0. 5 mol/L.
