Abstract: There were numerous strong intramolecular and intermolecular hydrogen bonds in the molecular structure of cellulose, which restricted the application of cellulose. To improve the reactivity and accessibility of cellulose, the activation pretreatment should be carried on the cellulose. And the research development of activation method for cellulose was reviewed mainly from three aspects of physical activation, chemical activation and physical-chemical activation. The action mechanisms of various activation methods were expounded, and the research results of recent cellulose activation pretreatment were also summarized. The different activation method for cellulose should be chosen according to different process in practical application.

Key words: cellulose, activation, pretreatment
