多级孔道结构木材的脱木质素改性及功能化应用研究进展

Research progress on delignification modification and functional application of hierarchical pore structure wood

木材是一种绿色环保、成本较低的天然材料,木材功能化改性是目前的研究热点。介绍了木材脱除组分、冷冻处理、高温碳化和浸渍处理的功能化改性方法。阐述了以木材孔道结构为出发点,对其进行功能化处理,并应用于油水分离、海水淡化、储能器件领域。结合相关研究方法及内容,提出木材功能化改性应用中存在的问题,并对其应用前景进行展望。

Wood is a natural material with low cost and environmental protection.The functional modification of wood has become a research hotspot.The functional modification methods of wood including removing components,freezing treatment,high-temperature carbonization and impregnation were introduced.Taking the wood pore structure as a starting point to carry out the functional treatment of wood and application to the fields of oil-water separation,seawater desalination and energy storage devices.By combining the relevant research methods and contents,the existing problems in the application of wood functional modification were presented,and the application prospect was discussed.
