木基金属复合材料的研究进展

Progress of the Development of Wood-Based Composite Materials

鉴于木材资源的有限性,限制对林木资源的砍伐迫在眉睫,因而,提高木材资源的高效利用显得尤为关键。基于木材固有的孔道结构和金属固有特性,木基金属复合材料可实现高效利用木材资源。本研究概述了木材和金属复合的发展进程、制备方法,以及其在抗静电、储能和疏水方面的最新研究成果及木基金属复合材料在L和X波段的电磁屏蔽性能。最后分析了木基金属复合材料的不足,展望了磁性木材在电磁屏蔽性能与棒状中空材料降解重金属离子的发展前景。

With the rapid development of science and technology,countries in the world have paid more attention to the ecological environment.Due to the limitation of timber resources,it is urgent to limit the cutting down of forest resources.Therefore,it is particularly important to improve the reuse rate of wooden materials.Based on the inherent pore structure of wooden materials and metal properties,efficient utilization of wooden resources can be realized via synthetic composites based wood.The article summarized the development of wood and metal composites,preparation methods,the latest research results in antistatic property,energy storage and hydrophobicity,as well as the electromagnetic shielding properties of wood-based metal composites in bands between L and X.Finally,the shortcomings of wood-based composites were analyzed,and the development and prospect of magnetic wood in electromagnetic shielding effectiveness and rod-shape hollow material degradation of heavy metal ions were prospected.
