Abstract
A durable solid and liquid repellant nanocomposite material is provided that includes a polymeric matrix comprising polyurethane or fluoropolyurethane that has a plurality of lubricating domains distributed therein. The lubricating domains are formed by a partial crosslinking reaction between a reactive oil comprising a first reactive group selected from the group consisting of: hydroxyl, amine, carboxylic acid, and combinations and a second reactive functional group selected from the group consisting of: isocyanate, hydroxyl, and combinations thereof on a polymeric precursor of the polymeric matrix. The nanocomposite material further includes a plurality of nanoparticles comprising silicon dioxide (SiO) distributed in the polymeric matrix. At least a portion of the plurality of nanoparticles are bonded to the polymeric matrix. Methods for forming the durable solid and liquid repellant material are also provided.
