Superhydrophobic anodized metals and method of making same

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