Current research of nanocellulose：preparation and its application

Abstract: In this paper, the advanced preparation methods of nanocellulose are reviewed and their advantages and disadvantages are compared, especially the application of using eutectic solvent to prepare nanocellulose instead of strong acid and strong base solvent is listed. In this paper, the wide application of nanocellulose in medicine, sewage treatment, electrochemistry, gas absorption and other fields are summarized, such as drug transport as a drug carrier and the construction of biological tissue scaffolds for medical field. Further research is needed, and the expectation of more green and efficient preparation of nanocellulose and its application prospect in more fields is expressed.
