A composition for selective anodization, comprising the substances amidosulphuric acid, magnesium sulphate and concentrated sulphuric acid as a base electrolyte and additionally sodium stannate and/or molybdenum oxide. A corresponding method of selectively anodizing a substrate or workpiece includes providing a substrate having a surface which is to be selectively coated, where the substrate is arranged in a tool and forms a coating cell, selectively bathing the surface with the composition for selective anodization, and applying an electric current between substrate (anode) and tool (cathode) for selective anodization of the surface.

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.
