Abstract

A method of modifying a surface of a substrate comprises: inkjet printing a fluoropolymer solution comprising vaporizable solvent and a non-vaporizable component comprising a dissolved solid fluoropolymer. The dissolved solid fluoropolymer comprises a reaction product of at least one monomer comprising vinylidene fluoride. Various articles may be produced according to the method.
