Abstract
This paper reports the fabrication of a lotus-effect coating by grafting epoxy (EP) resin on the surface of microsilica and nanosilica, respectively, and subsequent spraying. The coating shows the same structure and capability as lotus leaves, and shows a static contact angle as large as 165° and a sliding angle as small as 2.5°. SEM analysis shows that the hydrophobic capability depends on the surface structure of the coatings. This method may be suited for processing large scale or irregular surfaces.
