纤维素改性及其应用研究进展

Modification and Application of Cellulose

摘要: 纤维素是一种来源广泛、可生物降解和再生的天然聚合物。但是,其结构稳定,难溶于大多数溶剂,阻碍了纤维素产品的开发应用。纤维素改性不仅能有效提升其溶解性能,而且还可以丰富其应用性能,是目前推动纤维素应用的主要途径之一。为此,本文主要从纤维素改性的技术方法、已有改性纤维素的研究(包括酯类纤维素、醚类纤维素和接枝纤维素等)及其应用等方面进行综述,为纤维素改性的深入研究提供了有益的参考,推动纤维素的高值化利用。

Abstract: Cellulose is a natural widely available,biodegradable,and renewable polymer. It is great difficult to dissolve cellulose due to it owning massive intramolecular hydrogen bonds. Cellulose modification can improve its solubility,thereby being an important method to promote cellulose application. The techniques to modify cellulose and a few novel modified celluloses including cellulose ester,cellulose ether,grafted cellulose,etc. are reviewed. Hopefully,this review will become a significant reference for cellulose modification and promote cellulose to be utilized with a higher value.
