Abstract
As a green, abundant, and environmentally friendly natural polymer, cellulose has received continuous attention in environmental sustainability. Cellulose aerogel with 3D network, low density, high specific surface area, high porosity and biocompatibility have 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, and regenerated cellulose aerogels. In addition, the functionalization of cellulose aerogel in the adsorption application for the oil/water separation is present in detail. Finally, the future development trend of cellulose aerogel is proposed. This knowledge will bring great impacts on the field and assist the researchers to seek the new functions and applications of cellulose aerogels in the future.
