| Outline of Final Research Achievements |
We have studied on the creation of 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 new functions, such as large and reversible contractive force generation, which is comparable to human muscle, due to the coil-to-globule transition of poly(N-isopropylacrylamide) derived from NaCl in the surrounding aqueous solutions, reversible changes in optical anisotropy derived from unidirectional and plane orientations of clay nanosheet, ultra-high tensile modulus/strength as well as high responsive deswelling in NC gels with clay-silica-polymer ternary network, and high catalytic activity of Pt nanoparticles contained NC gel. In addition, we achieved the synthesis of initiator-free UV-NC gel, and abnormal increase in viscosity of alcohol aqueous solution by the presence of clay nanosheets.
