Abstract:

An article comprises a textured surface disposed on a substrate. The surface has an effective liquid wettability sufficient to generate, with a reference liquid, a contact angle in a range from about 120 to about 180. The surface comprises a material having a nominal liquid wettability sufficient to generate, with the reference liquid, a nominal contact angle in a range from about 60 to about 90, the material comprising at least one material selected from the group consisting of a polymer and a ceramic. The properties of the surface may include low-drag or low-friction, self-cleaning capability, and resistance to icing, fouling, and fogging, and the like. Methods of making such a surface are also described.
