Structure Control and Application of Nanocellulose Aerogels

Nanocellulose is a kind of renewable green material that comes mainly from plants. Nanocellulose aerogels have high porosity, excellent flexibility, and low thermal conductivity. They have broad application prospects in building insulation, sewage treatment, energy storage, aerospace, and other fields. The structure of nanocellulose aerogels has a significant influence on their properties, which further affects their application. In this paper, the present regulation methods of nanocellulose aerogel structure are reviewed, and the most widely used fields of nanocellulose aerogel are introduced in detail. In addition, research for improving the structure and applications of nanocellulose aerogels in the future is proposed.
