Abstract
The preparation of nanocellulose aerogels was introduced, several different preparation processes of cellulose nanofibers(NFC), such as high-pressure homogenization, ultrasonic method, Tempo oxidation,periodic acid oxidation, ionic liquid dissolution and organic alkali dissolution, were introduced. The directional freeze-drying technology were emphasized. Prospects and suggestions were made for the development and application of nano-cellulose aerogels, aiming to providing some reference for the more efficient development and utilization of nano-cellulose aerogels.
