摘　　要：在苯胺氧化过程中添加氧化石墨烯(GO),得到了GO/PANI(聚苯胺)复合材料;以水溶性环氧树脂乳液(WEP)为载体,采用机械共混法制得GO/PANI防腐蚀涂层。采用电化学方法研究了GO/PANI涂层的防腐蚀性能和机理。结果表明:当填料(GO/PANI)质量分数为1%时,胶膜耐水性较好,吸水率仅8%;含1%GO/PANI/的涂层的防腐蚀性能最好,且在H_(2)SO_(4)条件下制得含1%(GO/PANI)的复合涂层的防腐蚀性能最好。The GO/PANI(polyaniline)composite material was obtained by adding graphene oxide(GO)obtained by the hummer method during the oxidation process of aniline.GO/PANI anticorrosive coating was prepared by mechanical blending with water-soluble epoxy resin lotion(WEP)as carrier.Electrochemical methods were used to study the anti-corrosion performance and mechanism of GO/PANI coatings.The results showed that when the mass fraction of the filler(GO/PANI)was 1%,the adhesive film had high water resistance,with a water absorption rate of only 8%.The coating containing 1%GO/PANI had high corrosion resistance.And the anti-corrosion performance of the composite coating containing 1%(GO/PANI)prepared under H_(2)SO_(4)conditions was the best.
