Abstract

Abstract:

Cellulose is the most abundant renewable resource in nature and an ideal material for the preparation of economically sustainable polymers. Since natural cellulose has a highly crystalline aggregate structure and a dense hydrogen bonding network between molecular chains, its dissolution and processing are difficult, and its functional application is greatly limited. Recently, ionic liquids as novel solvent systems of cellulose have developed prosperously, providing a new platform for cellulose homogeneous processing and efficient utilization. This review summarizes the latest research progress on homogeneous processing of cellulose in ionic liquids, from the aspects of the types, characteristics of ionic liquids, the ability to dissolve cellulose, and the construction of cellulose materials based on “dissolution-regeneration” and “homogeneous derivatization”. It would provide references for the green and high-value conversion of cellulose resources in the future.

Key words: cellulose, ionic liquids, dissolution, regeneration, homogeneous derivatization, functional materials

摘要：

纤维素是自然界中储量最丰富的可再生资源，是制备经济可持续聚合物的理想材料。由于天然纤维素具有高度结晶的聚集态结构及分子链间致密的氢键网络，导致其溶解与加工困难，功能化应用受到了极大限制。近年来，离子液体作为新型绿色纤维素溶剂体系蓬勃发展，为纤维素均相加工与高效利用提供了崭新的平台。从离子液体种类、特性及溶解纤维素能力，基于“溶解再生”与“均相衍生”构建纤维素材料等方面综述了近年来纤维素在离子液体中均相加工的最新研究进展，为未来纤维素资源的绿色高值转化提供参考。
