Abstract: A one step process is described for forming metal nanoparticles in polymers at atmospheric pressure and room temperature or with mild heating and stirring. The inventive process includes addition of nanoparticle precursor salts, e.g. HAuCl4 or AgNO3 into a “reducing” polymer resin, for example polyurethane resins, derivitized polyurethanes, polyurethane acyrlates and combinations thereof. With stirring, often at room temperature, the salts are rapidly reduced to form metal nanoparticles, usually less than 100 nm in size and often in the size range of 20-40 nm, and even as small 2 nm, depending on the concentration of salt precursor used and the exact polymer composition. The resultant metal nanoparticle-containing polymer resins have a wide range of utility for making coatings and other polymeric materials with properties potentially useful for anti-bacterial use, optical coatings, or catalysts.
