An Overview of Cellulose Aerogel: Classification And Applications

As a green, abundant, and environmentally friendly natural polymer, cellulose has received continuous attention in the environmental sustainability. Cellulose aerogel with three-dimensional (3D) network, low density, high specific surface area, high porosity and biocompatibility has been widely applied in the adsorption and biomedicine fields. This review mainly focuses on the recent progress of cellulose aerogel. We have summarized the classifications of cellulose aerogels including bio-cellulose aerogels, nano-cellulose aerogels, cellulose derivatives aerogels
