Super-hydrophobic films with low electric resistance were prepared by coating the liquid containing both fluoro-acrylic resin and colloidal silica on an ITO-coated polymer film with the suitable repetition of a one-dimensional groove structure on the surface. The hydrophobicity was effectively enhanced by the roughness mixing effect. The formation of ITO layer on the surface of the base-film decreased the surface electric resistance and improved the durability of the super-hydrophobicity during outdoor exposure. The film prepared in current study satisfies the requirements of transparency, super-hydrophobicity, brightness enhancement property and long lifetime simultaneously.
