Superhydrophobic anodized metals and method of making same
Abstract
Methods for producing a superhydrophobic anodized surface including anodizing a surface of a substrate in an anodization acid to form a plurality of pores, etching the surface with an etchant to widen an edge of each of the plurality of pores; repeatedly anodizing the surface in the anodization acid and etching the surface with the etchant until the edges of the plurality of pores overlap to form a plurality of nano-sharp ridges, and coating the surface with a hydrophobic polymer to render the surface superhydrophobic, such that the surface exhibits a contact angle of at least 150 degrees with a drop of water. Articles including a surface having a series of nano-sharp pore ridges defined by a series of pores and a mum thick layer of a hydrophobic polymer on said surface.
