| Outline of Final Research Achievements |
Polymer hydrogels are utilized in various fields. However, conventional hydrogels are mechanical weak and brittle, and as a result their use often causes a serious problem in the industrial application. In this study, we succeded in fabrication of mechanically tough hydrogels composed of clay and a polymer in a enviromentally friendly process, and clarified key factors for acquistion of the mechanical toughness and influence of kinds of polymers on the mechanical properties of the hydrogels. Furtheremore, we found that the hydrogels were actuated by appling an electric field, and elucidated the mechanism of the electric actuation.
