摘要
随着木材工业的快速发展,以及木材原料的日益减少,利用农作物秸秆代替木材生产复合材料十分必要。然而由于大部分农作物秸秆表面含有蜡质层、二氧化硅及非极性抽提物,使其胶合困难。针对这一问题,国内外众多研究者在秸秆表面改性处理方面开展了大量的研究工作。总结得出,秸秆表面改性处理方法主要有机械处理法、湿热处理法、物理处理法、化学处理法以及生物处理法,通过比较认为低温等离子体的秸秆表面处理更具有优势和发展前景。
The renewable lignocellulosic sources for biocomposites has been received much attention in recent years because of shortage of forest resources and environment concerns.However,serious challenges have been encountered with the production of biocomposites from crop straws,because their surfaces are covered with the hydrophobic noncellulosic components including wax,silica and lipophilic extractives.A large number of surface treatment methods on straws have been made to improve its surface wettability.This paper reviewed several different treatments on straw,including mechanical,hot water,physical,chemical and biological treatment.Comparing with above the treatments,the low temperature plasm treatment was the most suitable for straw utilization.
