Cellulose-based aerogel is a new kind of functional biomass material
which combines the advantages of typical inorganic aerogels with ultralight weight
very high porosity and specific surface area and renewable biopolymers with abundance in nature
biocompatibility and biodegradability. This review first briefly introduced cellulose-based aerogels. Then the preparation of cellulose-based aerogels by using ionic liquids as solvents are discussed in detail
followed by their structure and properties. Finally
a perspective on this promising family of materials and the research that needs to be done in the future are briefly discussed.
