水溶性壳聚糖缓蚀剂缓蚀机理及其发展趋势

摘要

Chitosan contains lone pair electronic elements （such as O, N, S ）such as--NH2 ,-- COOH, etc., these elements or base group containing lone pair electrons can form the coordination key with empty track of metallic element directly, such as empty d track of Fe atom, and make the organic molecule absorb firmly on the metal surface, forming an protective film from corroding. So, careful studying of chitosan＇s inhibitory capability will be of a very important meaning. It was analyzed and summarized the corrosion mechanism of the metal materials in the hydrochloric acid medium and the research status in this article.%水溶性壳聚糖-含未配对电子元素（如O、N、S）的基团如-NH2、-COOH等。这些含有孤对电子的元素或基团可直接与金属元素上的空轨道形成配位键，使有机分子牢固吸附在金属表面，形成保护膜，防止金属腐蚀。因此，对水溶性壳聚糖进行缓蚀性能研究，具有重要的意义。文中对水溶性壳聚糖类缓蚀剂腐蚀的机理以及研究方向进行了分析和概述。
