摘要：

The electrochemical synthesis of poly(N-phenylpyrrole) film was achieved on pretreated iron and platinum electrodes in acetonitrile solutions containing 0.1 M N-phenylpyrrole as the monomer and 0.1 M tetrabutyl ammonium trifluoromethane sulfonate (Bu4NCF3SO3) as the supporting-salt The results showed that a surface treatment by 10 % aqueous nitric acid inhibits iron dissolution without preventing the N-phenylpyrrole oxidation. Very strongly adherent films were obtained at constant-potential, constant-current and cyclic voltammetry. XPS measurements, infrared (FT-IR) and electronic absorption (UV-vis) spectroscopies were used to characterize the iron and platinum-coated electrodes. Finally the anticorrosion properties of the POP film were evidenced.
