| Research Abstract |
We report on the preparation of anisotropic hydrogel particles. The hydrogel particles were prepared by aqueous free radical precipitation polymerization using acrylamide-derivatives and crosslinkers. Using the hydrogel particles, anisotropic hydrogel particles were prepared at air/water, oil/water, or solid/water interfaces. We revealed that the obtained hydrogel particles were assembled into chains under the certain conditions. To confirm that the phenomenon is due to the structure of the hydrogel particles, cationic and anionic microgels were mixed in aqueous solution. The oppositely charged hydrogel particles also showed particle-chains. We tried to prepare several types of anisotropic hydrogel particles at the interfaces.
