Article having a surface with low wettability and its method of making

An article (100) comprises a textured surface (120) disposed on a substrate (110). The surface (120) has an effective liquid wettability sufficient to generate, with a reference liquid (230), a contact angle (140) in a range from about 120° to about 180°. The surface (120) comprises a material havin...

Beschreibung
Zusammenfassung:	An article (100) comprises a textured surface (120) disposed on a substrate (110). The surface (120) has an effective liquid wettability sufficient to generate, with a reference liquid (230), a contact angle (140) in a range from about 120° to about 180°. The surface (120) comprises a material having a nominal liquid wettability sufficient to generate, with the reference liquid (230), a nominal contact angle (240) 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 (120) 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 (120) are also described.
