摘要
采用循环伏安法在不锈钢电极上制备出了聚苯胺(PANI),PANI-SiO2,PANI-TiO2和PANI-SiO2-TiO24种涂层,并运用极化曲线和交流阻抗技术对其防腐性能进行了探讨。结果表明:掺杂SiO2或TiO2,或者同时掺杂SiO2和TiO2,可以提高PANI的耐蚀能力,其中以掺入SiO2的效果最好。
Four coatings including polyaniline（PANI）,PANI-SiO2,PANI-TiO2 and PANI-SiO2-TiO2 were prepared on the stainless steel electrodes by adopting cyclic voltammetry,and these coatings＇ anticorrosion properties were characterized by polarization curve and alternate impedance spectrum.The results show that the anticorrosion performance of PANI are improved when SiO2,TiO2 or SiO2 and TiO2 are doped respectively,especially SiO2.
