| Outline of Final Research Achievements |
Nanocomposites containing block copolymers as matrix materials and nanofillers whose size were relatively larger than the size of microphase-separated structure of block copolymers were fabricated for achieving highly-functionalized nanocomposites, and at the same time the structures were analyzed. In detail, we fabricated the nanocomposites by adding the nanofillers to the aqueous solutions of block copolymers. It was revealed by the structural analysis of the nanocomposites that the microphase-separated structure of block copolymers in the presence of the nanofillers was different from the original structure of block copolymers without the nanofillers. It was also revealed that the nanocomposites showed thermoresponsive gelation properties and possessed a potential for biomedical applications.
