摘要
纤维素是自然界中最为丰富的可再生天然高分子材料,价格低廉,可生物降解,是最有潜力的绿色材料之一。纤维素分子链上含有大量羟基,形成分子间与分子内强烈的氢键网络,使得纤维素难于溶解在普通的溶剂中,难于加工,极大地限制了它的广泛应用。本文从纤维素的衍生物、接枝共聚物及凝胶的制备三方面,介绍了纤维素基功能材料的研究进展情况。通过化学改性的方法,减弱了纤维素分子间的氢键作用,得到结构与功能多样的纤维素材料,拓宽了纤维素的应用领域。
Cellulose is an abundant biomass resource with low cost and biodegradable properties, which is one of the most promising green materials. Cellulose, containing a lot of hydroxyl groups on the molecular chain to form strong interand intramolecular hydrogen bonding network, is difficult to dissolve in ordinary solvents, and is not easy to process, which greatly limits its wide applications. This paper introduces the research progress of cellulose functional materials from the preparations of cellulose derivatives, graft copolymers and gels. Cellulose-based functional materials, containing various structures and functions, have been prepared through weaken interand intramolecular hydrogen bonding in cellulose by chemical modifications, which broadens the application field of cellulose.
