Abstract:

This article first analyzes the excellent characteristics of cellulose nanocrystals. Following this, two chemical
modification methods are introduced with details, including small molecule chemical modification and grafting
copolymerization. On this basis, the applications and new advances in the use of cellulose nanocrystals to reinforce synthetic
polymer materials and natural polymer materials and their derivatives are covered. Furthermore, some suggestions on where
the field is likely to advance in the future are discussed.

Key words: cellulose nanocrystals, chemical modification, graft copolymerization, composite film
