Abstract
We developed novel polymer materials composed of thermoresponsive pNIPAAm main chain and photo-resnposive side chains of spirobenzopyran, and analyzed the photoresponsive characteristrics of the aqueous solutions of these copolymers. Further, we prepared various photoresponsive hydrogels composed of the copolymer, and investigated the effect of light irradiation on their properties. As a result, the copolymer exhibited quite unique response to light irradiation and the change in temperature and pH. Especially the drastic photo-induced dehydration was observed in low pH conditions, and photo-induced micro-relief formation was demonstrated using the hydrogel layer composed of the polymer.
