Abstract:Nanocellulose has a good application prospects in nanocomposite materials because of its large specific surface area, high mechanical strength, high crystallinity, good biocompatibility and other excellent properties. However, the characteristics of strong hydrophilic and easy to be reunited severely limit its application. This review described some methods developed recent years for improving the hydrophobicity and the dispersibility of nanocellulose in water and most organic solvents and their reaction mechanisms and research progresses for improving the hydrophobicity of nanocellulose, such as surface adsorption, esterification, coupling agents and ploymer grafting modifications are the methods and the surface adsorption, cationic modification, TEMPO oxidation, acetylation, coupling agents, ploymer grafting modifications are the methods for improving the dispersibility of nanocellulose. Additionally, both developing direction and application prospect of nanocellulose were introduced and forecasted in this review. |
