摘要
我国海洋工程装备制造业正处在生存与发展的关键阶段,防腐涂层是降低基材腐蚀速率、提升其服役寿命最有效的方式之一。导电聚合物涂层由于其绿色环保、制备简单等优点及独特的导电与防腐机制,使其在金属腐蚀防护领域得到了广泛的应用。本文归纳总结了导电聚合物涂层的防腐机制,介绍了采用化学氧化和电化学合成两种方法制备导电聚合物涂层的现状,重点阐述了导电聚合物涂层的掺杂改性、共聚改性、分层设计3种改性技术对涂层耐蚀性能的提升效果,最后提出了导电聚合物涂层在腐蚀防护领域可能存在的研究热点和发展趋势。
The marine engineering equipment manufacturing industry in China is in the critical stage of survival and development.The anti-corrosion coating is one of the most effective ways to reduce the corrosion rate of the substrate and improve its service life.Conductive polymers(CPs)coatings have been widely used in the field of metal corrosion protection due to its advantages of environmental protection,simple preparation and unique conductive and anticorrosive mechanism.This work summarizes the anticorrosion mechanism of CPs coatings,introduces the current situation of preparing conductive polymer coating by two methods of chemical oxidation and electrochemical synthesis,and focuses on the improvement effect of doping modification,copolymerization modification and layered design of CPs coatings on the corrosion resistance of the coating.Finally,the possible research hotspots and development trends of CPs coatings in the field of corrosion protection are proposed.
