Abstract

A method of producing a nanocomposite film includes generating a bilayer film including at least a first layer of at least one nanoparticle and a second layer of at least one material and annealing the bilayer film. A uniform nanocomposite film includes a plurality of nanoparticles dispersed in a polymer matrix, wherein the plurality of nanoparticles form at least 60% by volume of the polymer nanocomposite film.
