天然纤维表面改性及其在复合材料中的应用进展

Progress on Surface Modification of Natural Fiber and Its Application in Composites

综述了近年来天然纤维的表面改性方法,包括物理改性(蒸汽爆破、热处理、等离子处理等)、化学改性(碱处理、硅烷偶联剂处理、接枝共聚、乙酰化处理及其它改性方法),同时论述了这些改性方法对天然纤维增强树脂基复合材料物理力学性能的影响,研究表明,通过各种改性方法可改善天然纤维的表面性质,从而使其更好地与树脂基体结合,进而提高复合材料性能。

The modification methods of natural fibers in recent years were reviewed,including physical modification(steam explosion,heat treatment,plasma treatment and so on)and chemical modification(alkali treatment,silane coupling agent treatment,graft copolymerization,acetylation treatment and other modification methods).The effects of these modification methods on the physical and mechanical properties of natural fiber reinforced resin composites were also discussed.These researches show that these modification methods can improve the surface performance of natural fibers,so that they can better combine with resin matrix,and then improve the properties of composites.
