Abstract: Super absorbent material is a new type of functional polymer material with important application value. This article reviews the pretreatment,the graft modification and the compound modification of natural cellulose in recent years,and also introduces fungi cellulose. Pretreatment methods are emphasized,including alkalization,etherification,ionic liquids dispose and organic solvent dispose,the graft modification of cellulose and cellulose derivatives,and the preparation of super absorbent material by cellulose/silicate complex,cellulose/metal nanoparticles complex and cellulose/highpolymer complex. The cellulose-based super absorbent materials have a wide applied perspective in agriculture,pharmacy and environmental protection.

Key words: super absorbent material, cellulose, pretreatment, graft, composite
