木塑复合材料界面改性研究

Research Progress in Interface Modification of Wood-Plastic Composites

木塑复合材料在资源综合利用与环境保护方面具有优势,近年来得到快速发展。但是天然纤维的强吸水性以及与塑料间的相容性问题是木塑复合材料获得较好力学性能的关键因素。针对国内外的研究现状,从纤维和塑料界面相容性着手,着重介绍了几种常用的物理和化学改性方法。

The wood-plastic composite（ WPC） is used widely in the comprehensive utilization of natural resources and environmental protection in recent years. However, the main disadvantages of WPC are the poor compatibility between fiber and plastic and the relative high water sorption of natural fibers. Several commonly used methods of physical and chemical modifications for WPC at home and abroad are reviewed in this paper.
