Preparation and application of functionalized cellulose-based aerogels
Cellulose is one of the most abundant resources in nature.The third-generation aerogels prepared from cellulose have both the high porosity and large specific surface area of traditional aerogels and their own advan-tages.However,its inherent flammability,poor mechanical properties and low thermal stability limit its appli-cation.At present,the functionalization of cellulose aerogels and the development of a variety of functionalized composite aerogels have become a research hotspot.In this paper,the preparation process,functionalization methods and main application fields of cellulose aerogels are summarized.Finally,the problems of functional cellulose aerogels are discussed.
