摘要
为了让纤维素能在水和一般有机溶剂中溶解,并具有好的热可塑性,常对其进行化学改性,改变纤维素的结构特性,使其有利于加工成型。本文介绍了纤维素化学改性的基本原理,探讨了纤维素的溶解、活化与碱性润胀。通过纤维素羟基的氧化、酯化、醚化、接枝共聚和氮偶联反应对纤维素化学改性进行了综述,最后展望了纤维素化学改性的应用前景。
In order to make cellulose dissolve in water and general organic solvents, and has good heat plasticity, we often made chemical modification for cellulose, to change its structural characteristics, and make it easy to processing molding. Introducing the basic principle of cellulose chemical modification, discussing the dissolution, activation and alkaline swelling of cellulose. From oxidation, esterification, etherification, graft copolymerization and nitrogen coupling reaction of the cellulose hydroxyl groups, chemical modification of cellulose were summarized. Finally, application prospect of the cellulose chemical modification was forecasted.
