TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The conductive nanoparticles are metal nanowires including silver, copper, aluminum, gold, nickel, and stainless steel.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The monomer is chosen from acrylate, methacrylate, acrylic acid, methacrylic acid, acrylamide, methacrylamide, styrene, methyl styrene, epoxide, diacrylate, dimethacrylate, oligomer of acrylate and oligomer of methacrylate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The method further involves depositing releasing agent on the surface of the platform to facilitate the separation of the composite film from the platform, applying several conductive nanoparticles (B) to primary application of nanoparticles to form the porous conductive layer, annealing the nanoparticles deposit before coating the conductive layer with monomers, adding adhesion promoter to the monomers to promote bonding of the polymer film with the porous conductive layer, incorporating light transducing particles within the monomer to reduce the total internal reflection of light through the composite film, incorporating a light transducing additive in the monomer which absorbs light at one wavelength and re-emits light at longer wavelength, coating the composite film with protective layer of flexible monomer and curing the monomer coating before removal of the film from the platform, applying transparent polymer film onto the monomer coating before curing the monomers, coating the composite film with a protective layer before removal of the film from the platform, applying additional polymer film over the coating of monomers before the coating is cured and depositing a releasing agent on the surface of the platform to facilitate the separation of the composite film from the platform.
