Patent ID: 7396569

Claim:
A method for producing a nanocomposite film, said method comprising the steps of: contacting a substrate with at least one nanoparticle species by immersing the substrate in a solution containing the at least one nanoparticle species to form a nanoparticle layer on the substrate, wherein said at least one nanoparticle species comprises gold; contacting the nanoparticle-layered substrate with at least one polymer by immersing the nanoparticle-layered substrate into a solution containing the at least one polymer to form a polymer layer on the nanoparticle-layered substrate to form an elastomeric film on the substrate, wherein said at least one polymer comprises poly(urethane)-co-(siloxane); contacting the surface of elastomeric film with a resin; and treating the resin on the nanocomposite film to form an abrasion resistant matrix on the nanocomposite film.
