Research Progress in Cellulose Extraction, Modification and Application

As the fossil resource supply situation become more serious and the increasingly serious environment problems, the development of new carbon resource utilization has become an urgent task. Plant cellulose is the most abundant natural resource, which is renewable, nontoxic and degradable, has been paid much attrition by researchers of many countries. This paper reviews recent progress in plant cellulose extract and modification, especially in chemical modification of cellulose derivatives. And the article described cellulose modification technology about pretreatment. The applications of modified cellulose in the field of environmental protection, pharmaceutical, paint and other industries introduced as well. Finally, the current research hotspots of cellulose modification technology were prospected.
