Abstract
A hydrophobic disordered composite material having a protrusive surface feature includes a recessive phase and a protrusive phase, the recessive phase having a higher susceptibility to a preselected etchant than the protrusive phase, the composite material having an etched surface wherein the protrusive phase protrudes from the surface to form a protrusive surface feature, the protrusive feature being hydrophobic.
Claims10
An article having a hydrophobic surface, comprising:
- a composite base material comprising a first material and at least a second material different from said first material, wherein said first material is contiguous and said second material is contiguous, said first and second material forming an interpenetrating structure, and
- a plurality of spaced apart nanostructured surface features comprising said second material protruding from a surface of said interpenetrating structure, wherein said second material comprises a hydrophobic material or said surface features are coated with a hydrophobic coating layer.
