Fabrication of durable super hydrophobic surfaces on wood substrates with SiO2 and TiO2 nanoparticles

In this paper, a comparison was made between super hydrophobic surfaces resulted from SiO2 and TiO2 nanoparticles on chemical modification wood and bamboo Substrate. The super hydrophobicity of surface was evaluated based on its morphological properties, mechanical stability, long term stability, and self-cleaning ability by measuring WCA and SA angles. The super hydrophobicity of the surface was obtained by applying sandpaper mesh size 1500 and exposing the surface to the atmosphere for more than 180 days with a contact angle of 155±2° and a sliding angle of 6±2°, and surface showed a self –cleaning property. Taking into consideration the flexibility and simplicity of the method, it is a feasible and low-cost method to acquirable the lotus effect and demonstrated potential for practical applications.
