摘　　要：纤维素是资源丰富的多糖,为可降解,无毒,可再生的均聚物,在防腐蚀领域有很广的应用,但其作为缓蚀剂时,耐高温性能差。综述了纤维素基缓蚀剂的应用研究进展,介绍了其提供缓释保护的机理,并对提高其缓释性能的研究进行了概述。最后指出金属防腐蚀绿色环保型缓蚀剂——纤维素的开发与应用已取得了一定的研究成果,并将成为今后的研究重点。Cellulose is the most abundant natural polysaccharide in nature, which is a biodegradable, nontoxic and renewable homopolymer and is utilized for the corrosion inhibition of mild steel in acid medium. The research progress of cellulose -based corrosion inhibitor was reviewed and the anticorrosion mechanism of the coatings was introduced. Besides, the study of improving its sustained anti - corrosion performance was summarized. Finally, it was pointed out that the application and preparation of new-type environmental cellulosic inhibitor had made a certain progress, which would become the research emphasis in the future.
