Patent ID: 7736691

Claim:
A method for preparing functional organic particles comprising an organic polymeric matrix and functional nanoparticles dispersed in the organic polymeric matrix, which comprises: a) a step of preparing a mixture of monomers by mixing a monomer, a molecular weight modifier, and the functional nanoparticles; b) a first reaction step of adding a polymerization initiator to the mixture of the monomers and starting the first reaction to give a product of the first reaction; c) a second reaction step of mixing the product of the first reaction with a dispersant solution, and starting the second reaction by applying a centrifugal force of 50 to 5,000 G to give a product of the second reaction, so as to contain 70% to 100% of a total number of the functional nanoparticles in an outer region up to a point corresponding to 50% of a radius of the functional organic particle in a direction from a surface to a center of the functional organic particles; and d) a third reaction step of applying, to the product of the second reaction, a centrifugal force of 1 to 1000 G, weaker than the centrifugal force applied in the second reaction step.
