Thermoplastic elastomer hydrogels
Abstract
Provided herein is a block copolymer hydrogel, comprising a glass formed from a dry blend of polystyrene-poly(ethylene oxide) diblock copolymer (SO) and polystyrene-poly(ethylene oxide)-polystyrene triblock copolymer (SOS) in a molar ratio from between 95:5 and 1:99 SO/SOS and a liquid medium at a concentration between about 32:1 and about 2:1 liquid medium/SO—SOS by weight. The block copolymer hydrogel has a fatigue resistance to at least 500,000 compression cycles. Also provided are methods for forming the hydrogel.
