摘要
用较简单的化学氧化现场吸附聚合法（ｉｎ－ｓｉｔｕｐｏｌｙｍｅｒｉｚａｔｉｏｎ）制得了聚苯胺（ＰＡｎ）／聚乙烯醇（ＰＶＡ）导电复合膜．该膜具有较好的导电性和机械性能；其电导率可达５．８ｓ／ｃｍ，拉伸强度达１３ＭＰａ，断裂伸长率为１１０％左右．本文讨论了制备的各种条件对复合膜导电性能及力学性能的影响、稳定性及电化学活性；并采用循环伏安曲线、扫描电镜（ＳＥＭ）、ＦＴＩＲ谱及元素分析对该复合膜的结构和性能进行了表征．
conductive composite film of polyaniline (PAn) and polyvinyl alcohol (PVA) was prepared by in-situ polymerization of aniline on to PVA film. The composite film has high conductivity and good mechanical properties. Its conductivity can reach 5.8s/cm, its tensile strength 13 MPa and ultimate elongation 110%. The conditions of preparation, stability, mechanical properties and conductivity of the composites film were discussed. The composites film were characterics by CV curve. SEM and FTIR.
