Phase separation of polymers offers various morphologies ranging from nanometer to micrometer scales based on their compositions and interactions among polymer segments, which are well investigated in bulk systems. We have developed a method for fabricating polymer particles by simple solvent exchanging (Self-ORganized Precipitation, SORP) and found that phase separated structures formed in the polymer bend and block copolymer particles. Furthermore, unique morphologies, which different from original structures appeared in bulk systems, are found in small confined block copolymer particles. In this presentation, preparation of nanostructured polymer particles by SORP, and application for functional composite materials by incorporating functional inorganic nanoparticles into the nanostructured polymer particles will be discussed.
