Polymers are used in synthetic fibers, resins, and rubbers. We research the synthesis of functional polymer particles that can assume a variety of characteristics by chemically modifying the polymer particle surface where the particles have a uniform size.

Research and Achievements
One of our research is study of surface chemical modification of polymer particles. We have prepared mono-dispersed polymer particles using soap-free emulsion polymerization or RAFT polymerization. These surfaces on the particles are modified by color pigments, hydrophilic polymer chains and hydrophobic rigidity polythiophene. The other is study on property and electronic structure of poly-nuclear metal coordination complex with redox active ligands. The goal is to study of a new functional poly-nuclear metal complexes with spin transition behavior.
