摘　　要：采用溶胶-凝胶原位生长的方法制备超疏水木材,在木材表面形成一层纳米结构超疏水薄膜,水滴在木材表面接触角达到150.6°。采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、傅立叶变换红外光谱仪(FTIR)分别对超疏水木材样品的物相组成、表面形貌及表面化学官能团进行检测,分析表明木材的超疏水性是表面纳米级突起粗糙结构和乙烯基疏水基团共同作用的结果。Superhydrophobic wood was prepared by an in situ sol-gel process. The wood sur-face was covered by a thin layer of nanostructured superhydrophobic film,and the contact an-gle of water droplet on the wood surface reached 150.6＆#176; . The phase composition,surface mor-phology and chemical groups of the superhydrophobic wood sample were observed by X-ray diffraction （XRD）,scanning electron microscopy （SEM） and Fourier transform infrared spec-troscopy （FTIR）,respectively. The results revealed that the rough surface with nanoscale projec-tions combined with hydrophobic vinyl groups on the surface contribute to the superhydropho-bic property of the wood surface.
