Title: PHOTOTUNABLE THERMOPLASTIC ELASTOMER HYDROGEL NETWORKS
Abstract:
Provided herein is a thermoplastic elastomer hydrogel and methods of making such. The hydrogel comprises a glass formed from poly(styrene)-b-poly(ethylene oxide) in which the coronal chain end has been functionalized with photodimerizable groups (AB-photo) and a liquid medium at a concentration between about 32:1 and about 2:1 liquid medium/AB-photo by weight. The hydrogel has a fatigue resistance to at least 500,000 compression cycles.
