木材仿生超疏水功能化修饰研究进展∗

摘要

超疏水现象广泛存在自然界中，由于具有特殊的疏水及自清洁性能，在材料仿生构建领域引起了国内外学者的高度关注。木材仿生超疏水功能化修饰，能有效隔离水分与木材的接触，在木材及其产品室外长久利用、复杂高湿环境利用方面意义重大。从自然界超疏水现象与疏水理论基础出发，重点综述了木材超疏水仿生构建的主要方法，并对超疏水木材的性能进行探讨，提出了木材超疏水处理亟待解决的难题。%The phenomenon of superhydrophobic surfaces in natural exists wildly,which attracted highly atten-tion of researches at home and abroad on the area of bionic fabrication materials,for its strong hydrophobicity and self-cleaning property.The functional modification of superhydrophobicity on wood or wood products will segregate water and wood effectively,this has significance on outside long time utilization and complicated high humidity environment.This article starts from superhydrophobic phenomenon and theory,focuses on the prin-ciple methods of superhydrophobic fabrication,discusses properties,and proposes the challenge of superhydro-phobic treatment on wood surface.
