| 摘 要： | 基于木材天然的双重毛细管系统结构，金属醇盐可在木材"微/纳米容器"内进行溶胶-凝胶反应最终制备木材-无机复合材料。在溶胶-凝胶改良木材过程中，以金属醇盐为主要组分的前驱体溶液可通过涂覆、浸渍/真空加压浸渍、微波/超声波辅助等方式对木材进行改性，且木材密度、基材初始含水率、溶胶反应体系、溶胶粒径、溶胶pH值等对木材溶胶-凝胶改性效果都会有一定的影响。文中主要从制备方法和影响因素2个方面对溶胶-凝胶法功能性改良木材的研究现状进行归纳总结，并提出溶胶-凝胶功能性改良木材的应用前景和发展方向。

| Abstract: | Based on the dual capillary system structure of wood, wood-inorganic composite material can be prepared via sol-gel process of metal alkoxides within the micro/nanometer containers of wood.The precursor solutions in which metal alkoxides are the main components can be used to modify wood function through painting, spray, immersion, vacuum pressure impregnation or ultrasonic/microwave assisted impregnation.The effectiveness of wood function modification by sol-gel method depends on several factors, including density and initial moisture content of wood, sol system, particle size and pH of sol, etc.This paper reviewed the research on wood functional modification by sol-gel method in terms of the preparation methods and influencing factors, and proposed its application prospects and development direction. |
