Abstract
The present invention relates to methodologies for the self-assembly of nanoparticles onto a release support that is capable of covalent integration into flexible free-standing films. Such films display usefull constitutive properties, such as permittivity, permeability, electrical conductivity, thermal conductivity, and nonlinear optic properties. The type of property is dependant upon the type of nanoparticle incorporated into the compliant polymeric matrix. The compliant matrix may be any material that reacts with the components in the nanoparticle film and may be separated from the release substrate. The nanoparticles may be dispersed uniformly or spatially patterned throughout the self-assembled film.
Claims18
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.
