摘　　要：采用原位化学合成法制备对甲苯磺酸掺杂的聚苯胺/二氧化硅复合材料,并用红外光谱、扫描电镜和透射电镜表征其结构,以合成的聚苯胺/二氧化硅为功能组分,丙烯酸水性乳液为成膜物质,制成水性环保防腐涂料。用电化学测试技术研究复合水性防腐涂料对碳钢基材的防护效果。结果表明,复合水性防腐涂料使金属基体的腐蚀电位正移,具有较好的钝化效果,增强了耐蚀性。Polyaniline-SiO2 was in situ synthesized and doped by p-toluenesulfonic acid （p-TSA）. The com- posites were characterized by FTIR, SEM and TEM. The corrosion performance of polyaniline-SiO2 pigmented waterborne coating on carbon steel was studied by electrochemical testing technique in 3.5% NaCl solution. The tested results showed that a passivation effect and a positive shift of corrosion potential occurred due to the application of coating on metals and the anticorrosion property was enhanced.
