摘　　要：采用了恒电压法在不同的电解液中分别制备出硫酸(H2SO4)和复合酸(SSA+H2SO4)掺杂的聚苯胺(PAn)电极膜。通过循环伏安法(CV)、电化学阻抗谱(EIS)和塔菲尔曲线(TAF),对H2SO4和复合酸掺杂聚苯胺电极膜的电化学稳定性、导电性以及耐腐蚀性进行了研究与表征。结果表明,复合酸掺杂的PAn电极膜具有较好的电化学稳定性、导电性以及较强的耐腐蚀性,更能满足实际应用的要求。The polyaniline （PAn） electrode films doped with sulfuric acid （ H2SO4 ） and multiple acid （SSA ＋ H2SO4） were prepared using the potentiostatic method in the different electrolyte solution. The electrochemical stability, electrical conductivity and corrosion potential of polyaniline electrode films doped with H2SO4 and multiple acid were investigated and characterized by Cyclic Voltammetry, Electrochemical Impedance Spectroscopy（EIS） and Taler curve. The results showed that the electrochemical stability, electrical conductivity and corrosion potential of polyaniline electrode films doped with multiple acid were preferable, and it is easier to fufill the requirements in practice.
