| Outline of Final Research Achievements |
To obtain basic knowledge and design guidelines that can contribute to the development of highly functional diaper materials, polyvinyl alcohol gels were prepared as diaper material models, and the degree of swelling in aqueous solutions of sugars, surfactants, and dyes was measured. A characteristic solute concentration dependence of the degree of swelling was observed for each solute. Even very low concentrations of the solutes had a significant effect on the degree of swelling. The results were discussed in terms of interactions between macromolecules and small molecules, such as hydrogen bonding and hydrophobic interactions.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，含水高分子ゲルの膨潤度が，ゲルを浸している水溶液の溶質濃度に対して単調に変化するのではなく，極大などを示す場合があることを見いだした．そして，観察された膨潤度の濃度依存に関する知見を，溶質とゲル構成高分子の水和の観点から考察した．高齢者の衣生活を快適にするためには，オムツ素材に対して尿保持の安定性や消臭機能加工剤の固定安定性が要求される．本研究の知見と考察は，これらの要求を満たすオムツ素材の設計指針を与えているところに意義がある．
