1. A composite hydrogel comprising graphene oxide flakes distributed in and covalently bonded to a thermo-responsive hydrogel polymer, wherein the swelling ratio for the composite hydrogel is at least 50% greater than the swelling ratio for the thermo-responsive hydrogel polymer in the absence of the graphene oxide flakes at a temperature below the lowest critical solution temperature of the composite hydrogel.
