An Alkaline Hydrothermal Method to Synthesize Super-Hydrophobic Wood

Abstract:

A layer of sword-like super-hydrophobic film was fabricated on wood surface through an alkaline hydrothermal method. The super-hydrophobic property of the wood surface was measured by contact angle measurements (CA). The microstructure and chemical composition of the super-hydrophobic film was analyzed by scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FT-IR). Analytical characterization revealed that the micro-scale roughness sword-like particles uniformly erect on the wood surface and create the rough surface. Also, a monolayer of stearic acid was adsorbed on the rough surface which contributes to reduce the surface energy. With the combination of roughness and low surface energy of wood surface, the wood has turned its wetting property from hydrophilic into super-hydrophobic with a water contact angle 151^o, and the sliding angle is about 5^o.
