摘　　要：采用原位乳液聚合法,合成了聚苯胺/环氧树脂(PAn/EP)复合涂料,研究了聚合反应温度及体系pH值对其防腐性能的影响,并探讨了其防腐机理。结果表明,当反应温度为25℃、体系中pH=1时合成的PAn/EP复合涂料的防腐效果较好,并明显优于商品PAn/EP混合涂料。The effects of reaction temperature and pH value on the corrosion resistance of polyaniline/epoxy resin （PAn/EP） composite coatings, which were prepared by chemical in-situ polymerization, were investigated by Tafel measurement. And the anti-corrosion mechanism of polyaniline/epoxy resin composite coatings was also discussed. The experimental results show that when the reaction temperature is 25℃ and the pH value is 1, the corrosion resistance of the composite coating is satisfactory, and it is better than PAn/EP mixed coatings.
