  • POLYMER MACROPARTICLE OF WHICH SURFACE IS MODIFIED BY MESOPARTICLE AND NANOPARTICLE, NANOPARTICLE-POLYMER COMPOSITE USING THE SAME, AND PREPARATION THEREOF
    Publication number: 20090155592
    Abstract: According to the present invention, it is possible to easily provide a polymeric macroparticle of which surface is modified with mesoparticles and nanoparticles, by the step of adhering mesoparticles and nanoparticles to the surface of said polymeric macroparticle to form a composite structure of nanoparticle-mesoparticle-macroparticle, and optionally subjecting to a heat treatment to fix said mesoparticles and nanoparticles onto the surface of macroparticle. In addition, a nanoparticle-polymer composite materials can be provide from the above polymeric macroparticles of which surface is modified with mesoparticles and nanoparticles.
