摘　　要：在酸性环境下用化学氧化法合成了聚苯胺;制备了不同含量的本征态和掺杂态聚苯胺涂覆的碳钢试样,利用塔菲尔曲线比较了它们在质量分数为3.5%的NaCl和1 mol/L HCl溶液中的腐蚀行为。结果表明:当间甲酚固化剂作为溶剂、磷酸作为催化剂时,本征态聚苯胺涂层具有良好的防腐蚀性能;不同状态聚苯胺的防腐蚀性能与腐蚀介质有关,与聚苯胺的含量有关。Polyaniline was synthesized through chemical-oxidation in acid environment. Steel samples of eigenstate polyaniline or doped polyaniline with various contents were prepared and their corrosion behaviors in 3. 5% NaCl and 1 mol/L HCl solutions were compared using tafel plots. Results showed that the antieorrosion property of eigenstate polyaniline coating was better than that of doped one and anticorrosion property of polyaniline in various states was related with both medium and polyaniline content.
