Abstract: The present invention relates to new methods of producing polymer composite materials. More specifically, the invention involves a process in which layered materials including clays and other inorganic materials are dispersed into polymer systems to create polymer nanocomposite films. The resulting films exhibit improved resistance to fading when compared to polymer films that lack the additional layered materials.
