中文摘要：
采用化学氧化聚合法，以邻甲基苯胺为单体，过硫酸铵为氧化剂，HCl、HClO4、H2SO4为掺杂剂合成了掺杂态聚邻甲基苯胺。通过紫外、红外光谱对聚邻甲基苯胺的结构进行表征。对于涂覆含有本征态聚邻甲基苯胺（PotEB）或掺杂聚邻甲基苯胺／环氧树脂（EP）复合涂料的冷轧钢片涂层试样，测定了其物理性能和在3．5％（质量分数，下同）NaCI溶液中的电化学行为。结果表明，硫酸掺杂聚邻甲基苯胺（POT-HzS04）涂层的耐蚀性优于其他涂层的，POT-H1So4涂层的腐蚀电流最低（2．108×101mA／cm^2），腐蚀电位最高（-0．596V），电化学阻抗幅值达到4×10^5Ω·cm^2。
英文摘要：
Doped poly-o-touifine was prepared by chemical oxidation polymerization with o-toluidine as monomers, ammonium persulfate as oxidant and HC1, HClO4, H2SO4 as doping acid. The structures of the products were characterized by UV-visible and FT-IR spectra. The cold rolled steel piece was coated by poly-o-touifine （POT-EB） or doped poly-o-touifine and epoxy resin （EP） composite coatings. The physical performance and electrochemical performance in 3. 5wt% NaCL solution were tested. The results show that the corrosion resistane of coating containing POT-HzSO4/EP was better than others, which had a minimum corrosion current of 2. 108 × 10^-7 mA, a highest corrosion potential of -0. 596 V（SCE）, impedance value of 4× 10^5 Ω· cm^2.
