摘　　要：用循环伏安法在不锈钢上制备出聚苯胺膜,并研究修饰剂(有机硅烷偶联剂KH-560)对聚苯胺成膜的影响;用扫描电子显微镜、红外光谱和电化学方法研究聚苯胺的微观结构及电化学性能.结果表明,经修饰后的聚苯胺膜使不锈钢的腐蚀电位提高了70mV,腐蚀电流由1×10-6A下降到6.3×10-8A,大幅度提高不锈钢的抗腐蚀性能.Cyclic vohammetry was adopted to prepare polyaniline（Pan） coatings on stainless steel and the influence of modified agents （organo-silane coupling agent KH-560）on PAN coatings was also studied. The microstructure and performance of PAN were characterized by scanning electron microscopy, FTIR spectrum and electrochemistry method. The results show that modified PAN coatings shift the corrosion potential of stainless steel by 70 mV in noble direction and decrease the corrosion current two orders of magnetute from 1 × 10^-6A to 6.3 × 10^-8A. It markedly enhances corrosion resistance of stainless steel.
