Abstract:
1. A method for forming a system including polymer-encapsulated nanoparticles, the method comprising: mixing at least one of i) a polar, water-soluble, or water-miscible monomer, or ii) a polar, water-soluble, or water-miscible pre-polymer in a non-aqueous solvent and a plurality of nanoparticles having a polar surface selected from the group consisting of carbon black, copper phthalocyanine, titania, and silica to form a mixture of components; forming an inverse mini-emulsion including a continuous phase of a non-aqueous medium and a discontinuous phase of the mixture of components; and initiating polymerization of the at least one of the monomer or the prepolymer to form a polymer coating on each of the plurality of nanoparticles in the non-aqueous medium; wherein the forming of the inverse mini-emulsion is accomplished in the absence of water.
