聚合物缓蚀剂的研究现状与展望

Research Status and Prospect of Polymer Inhibitors

聚合物缓蚀剂易在金属底物表面形成单层或多层致密的保护膜,具有缓蚀效率高、缓蚀作用持久、不污染环境等优点,是缓蚀剂的重要发展方向之一。本文综述了有机膦酸聚合物、含氮聚合物、乙烯基聚合物以及其他聚合物缓蚀剂的研究进展以及缓蚀机理的研究方法,着重介绍了量子化学方法的应用,最后结合聚合物的研究现状做出了展望。

Generally polymer inhibitor molecule has multi-adsorptive group and is easy to form monolayer or multilayer protective film on metal surface, so that it has some advantages of low dose and high corrosion inhibition efficiency, long time of firm adsorption and low environmental pollution to become one of the important direction of corrosion inhibitor. Some polymer corrosion inhibitors, such as P-containing, N-containing and vinyl polymers were reviewed as well as the corrosion inhibition mechanism, emphasized on the application of quantum chemistry method. Finally the development of polymer corrosion inhibitor was prospected.
