NOVELTY - Preparation of graphite oxide/poly(N-isopropyl acrylamide) composite hydrogel comprises putting graphite oxide in water, dispersing via ultrasonic for 30-60 minutes to obtain graphene oxide colloid solution, adding graphene oxide colloid solution into N-isopropyl acrylamide, crosslinker, initiator 1, stirring and dissolving to obtain mixed solution; and charging nitrogen to fully remove oxygen, and mixed solution to remove oxygen, adding initiator 2, fully mixing at 25 plus minus 1 degrees C in water bath groove, and reacting to obtain the graphene oxide/poly (N-isopropyl acrylamide) hydrogel. USE - Method of preparation of graphite oxide/poly(N-isopropyl acrylamide) composite hydrogel (claimed).
