Abstract

Many metals rust when exposed to moisture and that rusting can cause the item that is made of that metal to break down. A superhydrophobic surface can repel liquids and keep metals from rusting longer. Superhydrophobic surfaces have existed in nature for a long time but are just beginning to be understood and manufactured for societal applications. They are manufactured by micro-texturing a surface that is either made from specific materials or is coated with a different material after the micro-texturing (see Figure 1). Both the material and the micro-geometry are important parameters in the surface‟s ability to repel liquids. Superhydrophobic surfaces may be used in the future as drag reducing surfaces, self-cleaning surfaces, novel heat transfer surfaces, condensers, etc. However, many of the fundamental physical laws associated with these surfaces are still largely unexplored.
