纳米晶纤维素改性及其功能性材料的研究进展

摘要

Cellulose nanocrystals (CNC) have some perfect properties, and the application of the modified CNC in functional materials has been a research focus. It stated the modification methods of CNC, including substitution with small molecules and different coupling agents, modification based on the ‘‘graft from’’ strategy with the radical polymerization of ring opening polymerization, Atom transfer radical polymerization and reversible addition-fragmentation chain transfer polymerization, adsorption modifications and some special chemical modifications.Research progresses in application of CNC in functional materials, such as biological drugs, polymer electrolytes, bio-inspired mechanically adaptive nanomaterials and so on.%纳米晶纤维素（CNC）是一种具有优异性能的纳米粒子，对CNC的改性和其功能性材料的应用一直是研究的热点。本文综述了CNC改性的方法，包括小分子改性、偶联剂改性，自由基开环接枝和ATRP接枝、RAFT接枝改性，吸附改性和一些特殊的化学改性，并分析了CNC功能性纳米材料在生物药物、聚合物电解质、生物激发力学适应性纳米材料方面的研究进展。
