目前,开发聚苯胺防腐涂料已成为高分子导电材料的应用和涂料研究开发领域的一个新的热点.为了研究本征态聚苯胺对丙烯酸涂层防腐性能的影响,制备了本征态聚苯胺质量分数分别为0%.1%,3%,5%及10%的聚苯胺／丙烯酸防腐涂层,应用Tafel极化曲线和电化学阻抗谱方法对比了其在3.5%NaCl溶液中的防腐性能.研究表明,聚苯胺在丙烯酸涂层中的含量对涂层的防腐性能有较大影响,聚苯胺质量分数为3%时,涂层具有最佳的防腐性能.
The study on polyaniline anticorrosive coatings in the use of conductive polymers and the study on coatings have received considerable attention in recent years. In order to research the influence of polyaniline on acrylic anticorrosive coating, the polyaniline /acrylic anticorrosive coating that the mass rate of emeraldine base form of polyani-line in coating was 0%,1.5%,3%,5%,10% were prepared, and theirs anticorrosive performance in 3. 5% NaCl solu-tion was studied by Tafel and EIS. The results indicate that the mass rate influences the anticorrosive performance of coating; The anticorrosive performance of coating is best when the mass rate of polyaniline in coating is 3%.
