Abstract:

      Cellulose-based functional material industrialization is regarded as an important direction in the transformation and upgrading of traditional pulp and paper industry. Nanocellulose-based aerogel is a type of light solid material prepared from nanocellulose， which has many advantages such as high porosity， large specific surface area， low density， and biodegradability， and widely application in fields of absorption and separation. In this study， the preparation methods of nanocellulose-based aerogels were summarized， the influence of the preparation process on the structure of nanocellulose-based aerogels was discussed， the application progress of nanocellulose-based aerogels in the fields of absorption and separation was reviewed， and the application prospect of nanocellulose-based aerogels was also suggested.
