Abstract

The present invention is directed toward a polymer and a method for making a polymer that has nanostructures incorporated into the matrix of the polymer. The method of the invention involves the following steps: mixing a precursor solution for the polymer with a precursor for the nanostructures to form a mixture; forming nanostructures in the mixture from the precursor of the nanostructures; and forming a polymer from the precursor solution of the polymer so that the nanostructures are incorporated into the polymer matrix.
