PPG Industries has received a patent for a method for generating metallic particles in situ in a solid polymer comprised of contacting the polymer with a solution comprised of a solvent, a metal salt and a free radical generator; infusing the solution into the solid polymer surface; removing the polymer from the solution that has not been infused into the polymer surface; and exposing the polymer to actinic radiation to generate metallic particles in situ in the surface regions of the polymer.
