| Outline of Final Research Achievements |
Stimuli-responsive hydrogel microspheres (microgels) with various nanostructures were developed. By using a series of the developed microgels, it was found that the self-organized structures of the microgels at fluid interfaces can be controlled by changing the characteristics of the soft microgels (e.g., shape, charge density and softness). In particular, it was found that hydrogel microellipsoids can be synthesized by seeded precipitation polymerization of polyacrylamide-derivatives on ellipsoidal solid core, and by using the anisotropic microgels, control of the dimensionality of the assembled structures was achieved at air/water interface of sessile droplets. Finally, on/off switching of the microgel's volume oscillation was realized, and can be used for self-organization of microgels toward precisely controlled microstructures.
