| Outline of Final Research Achievements |
We report the preparation and characterization of novel hybrid hydrogel microspheres having polymer network structure multipully-crosslinked with silica nanoparticles. The hydrogel microspheres were prepared in a facile manner involved simple mixing of an aqueous mixture of a water-soluble copolymer having reactive side chains with silica nanoparticles in water-in-oil suspension. The size of hydrogel particles can be facilely controlled by the viscosity of suspension media and composition of hybrid hydrogels. As expected, the properties of the hydrogel particles such as mechanical strength and swelling property are strongly affected by the polymer network structure which is controlled by the polymer chain length and the number of crosslinking points. Such high tunable hydrogel microspheres are expected to be used in various application fields such as medical and industrial applications.
