Outline of Final Research Achievements

In this study, we aimed to develop advanced functional materials used in the fields of energy and medicine by controlling the molecular weight and crosslinking structure of the polymer by quantum beam irradiation. In the development of a polyelectrolyte membrane for next-generation alkaline fuel cells using radiation graft technology, we succeeded in improving chemical stability (alkali resistance / radical resistance) by introducing a crosslinked structure into an anionic conductive polymer. In the development of polymer gel dosimeters for radiotherapy, we succeeded in increasing the sensitivity by optimizing the concentration and composition ratio of the chemicals.

Academic Significance and Societal Importance of the Research Achievements

本研究により得られた知見は、今後の高イオン伝導、低含水、且つ高耐久性の電解質膜開発やポリマーゲル線量計材料の高度化の指針となるため、学術的にも意義がある。また、作製した高耐久アニオン伝導高分子電解質膜は、次世代蓄電池である亜鉛空気二次電池への適用も検討されており、将来、脱炭素社会の構築やSDGsの達成に貢献できるものと期待される。
