摘要
采用不同的功能质子酸对化学氧化法合成的聚苯胺进行二次掺杂,比较了不同掺杂态聚苯胺的溶解性能;采用开路电位法和极化曲线法考查聚苯胺/环氧复合涂膜的防腐蚀性能。结果表明,用十二烷基苯磺酸钠(DBSA)掺杂的聚苯胺涂料具有很好的防腐蚀性能,涂覆该涂料的平衡开路电位比空白试样提高了近100 mV。
Polyaniline prepared by chemical oxidation polymerization was doped secondarily with various functional proton acids. The solubility of doped polyaniline was studied. Open circuit potential (OCP) and polarization curves test were employed to characterize the anticorrosion performance of polyaniline/epoxy coatings. The results indicated that polyaniline doped with sodium dodecyl benzene sulfonate (DBSA) had the best corrosion resistance, and the OCP of this polyaniline coating was 100 mV higher than that of the blank sample.
