Outline of Final Research Achievements

We have studied on the new functions and development of new hydrogel materials based on the modification of organic (polymer)/inorganic (clay) network structure of nanocomposite (NC) gel. Consequently, we found instant and strong adhesive behavior of NC gels toward hydrophilic porous polymer or ceramic materials. Well-dispersed, non-aggregated spherical monometallic and bimetallic nanoparticles were strongly immobilized within the polymer-clay network of NC gels. Mixed aqueous solution of a specific polymer and clay exhibited a large viscosity maximum and gelation behavior. Also, clay aqueous solution with specific pH exhibited large and complex time-dependent viscosity changes in the static state after the cessation of stirring. Further, after no real progress has been achieved for over 147 years, we discovered new aqueous solutions that exhibit much lower viscosities than water and unique viscosity-composition curves.

Academic Significance and Societal Importance of the Research Achievements

高分子ヒドロゲルは、医療・医薬・電子・土木・農業など幅広い分野で用いられる水を主成分とする材料であり、ソフトでウェットな機能性材料として期待されている。我々は、無機粘土鉱物との複合により、弱くて脆いというヒドロゲルの常識を打ち破った新たなヒドロゲル(ナノコンポジット(NC)ゲル)を開発した。本研究では、その機能性を拡大し、また、新規なNCゲルを開発することに取り組んだ。また、水溶液の詳細検討により、水より低粘度を示す水溶液を147年ぶりに発見した。
