| Research Abstract |
We newly designed isopropylacrylamide(IPAAm)-based copolymers randomly containing carboxyl or hydroxyl groups. Their temperature-responsive behavior on comonomer composition, salt concentration and pH of the solution was precisely investigated. Furthermore, we studied coacervate droplet formation and corresponding micrometer-sized hydrogel by effective cross-linking reaction. Using the two kinds of IPAAm-based copolymer with different functional moieties, the obtained coacervate was completely fusion-type and the hydrogel showed semi-interpenetrating polymer network structure. Furthermore, the obtained hydrogel showed very sensitive temperature-and pH-responsive properties.
