天然高分子在金属缓蚀保护的应用进展

Progress in the Application of Natural Polymers as Metal Corrosion Inhibitors

综述了纤维素、壳聚糖,淀粉以及其他生物高分子作为缓蚀剂的研究进展,并介绍了天然高分子提供缓蚀保护的机理,最后结合聚合物的研究现状做出了展望,绿色环保型缓蚀剂的开发与应用也取得了一定的研究成果,并将成为今后的研究重点。

Inhibitors is the one of the best options for protecting metals and alloys against corrosion. However,due to the toxicity of either organic or inorganic corrosion inhibitors to the environment and the health of human beings,green,we are searching for safer and more eco-friendly corrosion inhibitors,most of which are biodegradable and contain neither heavy metals nor toxic compounds.With the requirements of green and sustainable development,the use of natural polymers as corrosion inhibitors has attracted attention and has gained wide acceptance in recent years,and has become one of the important developing directions of corrosion inhibitors.Research progresses in using cellulose,chitosan,starch and other biological macro- molecules as corrosion inhibitors were reviewed and the anticorrosion mechanism of natural polymers as the coatings was introduced.Finally the development of polymers as corrosion inhibitors was prospected,and achievements were summarized made in the research and application of green and eco-friendly inhibitors, which,as pointed out here,will be the research emphasis in the future.
