Abstract :
In this study, nanoimprinting on ZnO sol-gel film is used to prepare regular nanostructure for tuning the wetting properties of the coatings, which is a very simple and relatively inexpensive method to produce high quality patterned film. However, the hydrophobicity of the surfaces comes from its rib patterns, and the surface roughness not only contributes to the very large fraction of air trapped on the surface but also interrupt the three-phase contact line of water droplet on the surface.
