Outline of Final Research Achievements

Diblock and triblock copolymers containing polyvinyl catechol (PVCa) moieties were successfully synthesized by using reversible-addition fragmentation transfer (RAFT) polymerization process. Iron oxide nanoparticles and silver nanoparticles were co-assembled in the PVCa phases by using adhesion and reduction properties of catechol moieties, and the composite films show unique magneto-optical effect in the wavelength of the plasmonic absorption band of silver nanoparticles. From these results, we have succeeded in the development of a new fabrication process of metamaterials by using biomimetic block copolymers.
