A composite wooden material with superhydrophobicity was obtained by applying various inorganic particles with micro/nano structures on the wood surfaces. The surface energy of the treated wooded materials were dramatically changed. Owing to the virtue of the coupling agent, which plays an important part in bonding the inorganic particles and the wood surfaces, the structure of the superhydrophobic thin film on the wood surface is extremely stable. The microstructure of superhydrophobic wood was characterized by scanning electron microscopy (SEM), the images showed that the modified wood was covered with a uniform layer of inorganic particles, generating a rough structure on the wood surface. The superhydrophobic performance of the modified wood was characterized by water contact angle measurements. The measurements showed that the wettability of modified wood samples transformed from hydrophilicity to superhydrophobicity with the water contact angles of 153 ± 1°. This method can be applied to various wooden materials for broad applications.
