| Outline of Final Research Achievements |
Swelling behavior of polymer gel materials was studied in order to obtain design guidelines for highly functional diaper materials. Polyvinyl alcohol (PVA) gel was used as a diaper model material. The swelling degree of PVA gels in aqueous solutions of amino acids and saccharides was measured. The interactions between the hydroxyl groups of PVA and the solutes through water molecules influenced the swelling of the gels. In addition, the sorption of direct dyes for charged PVA gels, which is the basis for functionalization of a super absorbent polymer, was also investigated.
