摘要: 提出了聚苯胺薄膜电极上循环伏安法可逆波方程式,对伏安曲线的性质进行了详细的讨论,聚苯胺薄膜电极是利用浓度为1.09mol/L苯胺溶液(内含2.0mol/LHCl)在铂电极上用恒电流(0.01~0.1mA/cm2)使苯胺发生氧化反应进而经聚合获得。结果表明,该法得到的聚苯胺膜具有良好的均匀度和单一性,在10mol/LHCl底液中获得的循环伏安曲线与理论结果相符合。

Abstract: The theoretical equation of reversible wave in cyclic linear sweep voltammetry on polyaniline thin film-coated electrode is described. The characters of the voltammogram curves are discussed in detail.Polyaniline films were deposited on the Pt electrode by oxidative polymerization of aniline at 0.010.10 mA/cm2 in 2.0 mol/L HCl solution containing 1.09mol/Lmonomer. It has been found that the polyaniline film prepared in this manner was homogeneous and uniform in its thickness.In order to examine the validity of the equation, experimental studies were carried out at the PANIthin film-coated electrode in 10mol/L HCl solution.The observed results are in good agreement with the theoretical ones.
