▎ 摘　　要

NOVELTY - The method involves preparing oxidation graphene water dispersing liquid. The porous carbon material is grinded and added to graphite water dispersion, oxidation and ultrasonic dispersion. The graphene/porous carbon composite hydrogel is obtained by taking oxidation graphene and mixed dispersion of porous carbon material. The dispersing liquid concentration of the oxidation graphene water is 1 to 3 mg/ml. The porous carbon material and mass ratio of oxidation graphene is 1 to 10. The porous carbon material is lucid ganoderma medicine slag base porous carbon. USE - Graphene/porous carbon composite hydrogel, air gel preparation method. ADVANTAGE - The graphene is realized and the combination of porous carbon material realization of graphene is effective. The internal resistance is small and big capacity is ensured. The stability is good. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene/porous carbon composite gas gel. DESCRIPTION OF DRAWING(S) - The drawing shows the screenshot of graphene/porous carbon composite hydrogel and object image.
