摘　　要：纤维素基高吸水材料主要通过醚化和交联、接枝共聚和复合改性的方法制备,其中复合改性主要有纤维素/高分子复合以及纤维素/无机物复合两种。改性后,材料的吸水倍率可达几百至几千倍,同时还具备可生物降解性能,因此应用前景广阔。Cellulose-based superabsorbent materials are mainly prepared by etherification and crosslinking,graft copolymerization and composite modification.Among them,the composite modification mainly includes cellulose/polymer composite and cellulose/inorganic composite.After modification,the water absorption rate of material can reach several hundred to several thousand times.Cellulose-based water absorbing materials also have biodegradability,so the application prospect is broad.
