Superhydrophobic substances were favored in wood protection. Superhydrophobic treatment of wood is of great significance for improving the service life of wood and expanding its application fields, such as improving dimensional stability, durability, UV stability, and reducing wetting. The superhydrophobic phenomenon is attributed to the interaction of micro/nano hierarchical structure and low surface energy substances of the wood surface. This is the common method for obtaining superhydrophobic wood. The article introduces the common preparation methods of superhydrophobic wood material coatings and their mechanisms. These techniques include lithography, sol-gel methods, graft copolymerization, chemical vapor deposition, etc. The latest research progress of superhydrophobic wood material coatings application at domestic and overseas is reviewed, and the current status of superhydrophobic coating application in wood materials and construction is summarized. Finally, superhydrophobic on wood in the field of applied research is presented, and the development trend in the field of functional improvement of wood is foreseen.
超疏水物质在木材保护方面备受青睐。对木材进行超疏水处理对于提高木材的使用寿命以及拓展其应用领域具有重要意义，例如提高尺寸稳定性、耐久性、紫外线稳定性以及减少润湿性。超疏水现象归因于木材表面微/纳层级结构与低表面能物质的相互作用。这是获得超疏水木材的常用方法。文章介绍了超疏水木材材料涂层的常见制备方法及其机理。这些技术包括光刻法、溶胶-凝胶法、接枝共聚法、化学气相沉积法等。综述了国内外超疏水木材材料涂层应用的最新研究进展，并总结了超疏水涂层在木材材料及建筑领域的应用现状。最后，介绍了超疏水在木材应用研究领域的情况，并展望了木材功能改进领域的发展趋势。
