STIMULATION-RESPONSIVE HYDROGEL, PROCESS FOR PRODUCING STIMULATION-RESPONSIVE HYDROGEL AND POLYMER ACTUATOR UTILIZING STIMULATION-RESPONSIVE HYDROGEL

摘要

A stimulation-responsive hydrogel that has a high breaking strength and an excellent stimulation-responsive capability, excelling in stability over time. There is provided a stimulation-responsive hydrogel capable of absorbing water to thereby swell, resulting in gelation, the stimulation-responsive hydrogel having its swelling degree and volume changed by stimulation, wherein a polymer insoluble in water is contained with a phase separation structure.
