Outline of Final Research Achievements |
To improve mechanical strength of the hydrogels and to give optical functionality to the gels, two issues were studied in this study. 1. Hydrogels, in which organic polymers and porous inorganic particles were topologically conjugated, were prepared. It was showed that strengthening could be performed with little loss of the extensibility when the particle size is less than 1 um. 2. Metal nanostructures were formed on the solid substrates and they were transferred onto the hydrogel through the in situ polymerization on this substrate. Interparticle distance of the metal nanostructures on the gel could be tuned by the volume change of the hydrogel through the change of swelling state.
