纤维素纳米纤维增强聚合物复合材料研究进展

摘要

Cellulose nanofiber (CNF) has rapidly developed in reinforcing polymer to fabricate nanocomposites due to its unique web-like structure and special properties.In this paper,the preparation and the characteristics of CNF were briefly introduced.Then,the researches on the surface chemical modification of CNF including surface derivatization,surface grafting and addition coupling agent were presented.The characteristics of CNF after modification were also introduced.Next,the research advances of the polymer nanocomposites that derived from PVA,PLA,epoxy and PF reinforced with CNF were reviewed respectively.Last,the future research directions of CNF reinforced polymer nanocomposites were prospected.%纤维素纳米纤维(cellulose nanofiber,本文缩写为CNF)因其独特的网状结构和性能特点,在增强聚合物制备复合材料方面发展迅速.简述CNF的制备及特征;然后从改善团聚、提高界面相容性的角度,介绍对CNF进行表面衍生化、表面接枝和添加偶联剂等表面化学改性研究及改性后CNF的性能特点;简述利用CNF增强聚乙烯醇、聚乳酸、环氧树脂、酚醛树脂等聚合物的研究进展;最后对CNF增强聚合物复合材料今后的主要研究方向进行展望.
