Outline of Final Research Achievements

We have succeeded in synthesizing a polycarbonate with a hyperbranched structure. The obtained hyperbranched polycarbonate not only can dissolve more lithium salts than linear polymers, but also show high ionic conductivity and can be a polymer electrolyte superior to previous reported linear polymers. This research provides a design concept for new material creation.

Academic Significance and Societal Importance of the Research Achievements

化学構造に高度に枝分かれした構造を導入した高分子を用いることで高分子電解質の物性を制御することを試みた。分岐構造の導入により、電解質の電位電導度が向上する現象が見られた。より詳細に評価することにより、分岐構造の導入が高分子鎖の活性化エネルギーを低下させうることが明らかとなった。このことから、より高いイオン伝導度を示す高分子の化学構造に対して分岐が影響することを示し、新たな分子設計の指針を与えた。
