聚苯胺在防腐方面的研究及应用现状

论文摘要

聚苯胺(PANI)具有良好的热稳定性和环境稳定性,经掺杂后,具有导电性及电化学性,可作为填料应用于金属防腐领域。但其分子链骨架刚性强、分子间作用力大,不易加工成型,不溶于常规的有机溶剂,当其作为填料应用到防腐涂料中存在溶解性、分散性差且与金属基底附着力不强等缺点,如能对其进行合理有效的改性,则可解决上述问题。简要探讨了溶液聚合法、反相微乳液聚合法、模板聚合法以及电化学聚合法等PANI的制备方法,并针对PANI在防腐涂料应用中存在的问题,重点阐述了PANI的质子酸掺杂改性及复合改性等不同改性方法,通过掺杂不同的质子酸对PANI进行化学改性,可降低PANI分子链之间的相互作用,从而提高其溶解性、导电性和防腐性能。将不同性能的材料与PANI进行复合改性,改善分子间作用力,能提高其加工性,从而更好的应用于金属的腐蚀防护工作。最后介绍了PANI在腐蚀防护过程中的作用、在防腐蚀涂料中的应用及相关理论的研究现状,并指出PANI防腐涂层的研究重点和发展方向。
