It indicates that the PANI particles constituted films are ball like or ellipsoid like; the film takes on tertiary structure; HClO4 servers as both an acid medium and a dopant; the crystallizability of the film seems poor; the relationship between film thickness and acid concentration is not in linearity; the conductivity of the film is on a level with semiconductor, whose value depend more on film appearance than acidity of acid medium; the film starts dedoping at 67.3℃ and end at 277.2℃.

结果表明，构成薄膜的聚苯胺粒子呈球型或椭球型；薄膜具有三级结构特征；高氯酸不仅作为介质酸，同时作为掺杂剂；薄膜的结晶性能不佳；薄膜厚度与介质酸的浓度并非线性关系；薄膜的电导率处于半导体水平；电导率大小与无机介质酸的酸性强弱有一定关系，与表面形貌关系更为紧密；高氯酸掺杂聚苯胺薄膜在67.3℃时开始脱掺杂，在277.2℃脱除完全。
