纤维素基缓蚀剂的缓释机理与应用进展

Mechanism and Application Progress of Cellulosic Corrosion Inhibitor

简要介绍了纤维素及其衍生物的分类及其特性,综述归纳了纤维素的缓蚀机理,系统概述了植物纤维素及其衍生物,纳米纤维素在缓蚀系统中的多种缓蚀作用,同时以植物纤维素和纳米纤维素的结构特性为依据,讨论了细菌纤维素在金属缓蚀系统中的应用前景。最后提出羧甲基纤维素与羟乙基纤维素及它们各自的衍生物应用范围广,但受温度影响较大。纤维素纳米晶体在金属防护方面有很好的应用前景,也是未来研究的重点。细菌纤维素有望成为一种高效、绿色的新型缓蚀剂,但目前还未引起研究人员足够的重视,对其制备方法和缓释机理还需要进行深入研究。

The classification and properties of cellulose and its derivatives were briefly introduced and he the corrosion inhibition mechanism of cellulose was reviewed and summarized.Then,the various corrosion inhibition effects of plant cellulose and its derivatives as well as nano-cellulose in the corrosion inhibition system were systematically summarized.At the same time,based on the structural characteristics of plant cellulose and nano-cellulose,the application prospect of bacterial cellulose in metal corrosion inhibition system was discussed.Finally,it was proposed that carboxymethyl cellulose,hydroxyethyl cellulose and their derivatives were widely used,but greatly affected by temperature.Cellulose nanocrystals have good application prospects in metal protection,and are also the focus of future research.Bacterial cellulose is expected to be a new type of corrosion inhibitor with high efficiency and green property,but has not been paid enough attention by researchers.The preparation method and slow-release mechanism of bacterial cellulose need to be further studied.
