Coating Surfaces with Superhydrophobic Powder
Superhydrophilic and superhydrophobic fabrics are taught having a superhydrophilic or superhydrophobic powder disposed on the fabric. The superhydrophilic powder has at least one material of sodium borosilicate glass and porous diatomaceous earth. The powder material has a contiguous interpenetrating structure with a plurality of spaced apart nanostructured surface features. The superhydrophilic powder is switched to superhydrophobic by adding at least one superhydrophobic material of perfluorinated organics, fluorinated organics, and self-assembled monolayers.
