Methods of manipulating surfaces for extreme hydrophilic, hydrophobic or omniphobic behavior and applications thereof

A surface modification method involves oxidizing a surface of a material and etching the surface, and repeating the oxidizing and etching one or more times until desired nanostructures are created in the surface. The desired nanostructures make the nanostructured surface superhydrophilic. Hydrophili...

Beschreibung
Zusammenfassung:	A surface modification method involves oxidizing a surface of a material and etching the surface, and repeating the oxidizing and etching one or more times until desired nanostructures are created in the surface. The desired nanostructures make the nanostructured surface superhydrophilic. Hydrophilic properties of the surface may be further developed by application of hydrophilic material, and by application of functionalized micro/nanoparticles to the hydrophilic material. Substitution of hydrophobic material for the hydrophilic material creates a superhydrophobic surface. Further addition of an omniphobic coating to the functionalized micro/nanoparticles creates a durable omniphobic surface.
