摘　　要：本文用化学聚合法合成了在N－甲基吡咯烷酮（NMP）中可溶的聚苯胺（PANI）。通过溶液法定量（浓度与体积）制膜，对PANI膜修饰电极的循环伏安（CV）性质进行了研究，证实了PANI膜在10．0mol／LHCl的介质中，－0．15～0．65V（vs．SCE）的电位范围内氧化还原单元为八隅体单元。比较了恒电流聚合与化学聚合所得的聚苯胺的CV性质，发现两者有很好的一致性。Polyaniline(PANI) soluble N-methyl-2-pyrrolidone was chemically synthesized in this paper. The PANI film was formed quantitatively by a solution method and its cyclic voltammetic properties were investigated. The octamer redox unit of PANI film in the potential range of - 0. 15~0. 65 V(vs. SCE) in 10 mol/L HCl was verified. The cyclic voltammetric behaviors of PANI films prepared by electrochemical and chemical methods were compared quantitatively. They agreed with each other.
