Abstract
A fibrillar, nanotextured coating is deposited on a substrate by contacting the substrate with a reaction mixture comprising a reagent which is hydrolyzable to produced a cross-linked reaction product, and a first solvent which solvates the reagent and the reaction product. The reagent is hydrolyzed so as to provide a cross-linked reaction product which is bonded to the substrate. The substrate is then contacted with a second solvent which is a non-solvent for the reaction product so as to cause nanoscopic phase separation of the reaction product, resulting in the formation of a fibrillar nanotextured coating which is bonded to the substrate. The thus produced coating may be subjected to further chemical modification. The method may be utilized to produce superhydrophobic coatings. Also disclosed are coatings made by the method of the present invention.
