Outline of Final Research Achievements

In this study, I aimed to extend the concept of a polymer Ionics using a lyotropic liquid crystal (LC) property in sulfonated polyimide thin films and other polymers by elucidating the structural factors. The alkyl-sulfonated group at the side chain strongly contributes to make an organized structure due to the lyotropic LC property. Regarding the rigidity and flatness of the main chain, it was confirmed that they are also important for organized structures because the alicyclic skeleton did not show the organized structure. On the other hand, it was also found that the alicyclic skeleton can be structurally organized by increasing the molecular weight.

Academic Significance and Societal Importance of the Research Achievements

高プロトン伝導性の高分子には長距離秩序がないことから(アモルファス的な構造)、ミクロなナノ構造とマクロな物性であるプロトン伝導度の議論は距離的なスケールで直接的には十分に議論されていなかった。本研究成果は、広義のライオトロピック液晶性を用いた高分子の組織構造化を検討することで、構造とプロトン伝導の相関の議論を可能にした。また、従来とは全く異なる高プロトン伝導性高分子のための新しい分子設計指針を拓き、高分子イオニクスの学問分野が拡張された。
