Superhydrophobic wood was prepared by an in situ sol-gel process. The wood surface was covered by a thin layer of nanostructured superhydrophobic film，and the contact angle of water droplet on the wood surface reached 150.6°. The phase composition，surface morphology and chemical groups of the superhydrophobic wood sample were observed by X-ray diffraction (XRD)，scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR)，respectively. The results revealed that the rough surface with nanoscale projections combined with hydrophobic vinyl groups on the surface contribute to the superhydrophobic property of the wood surface.
