▎ 摘　　要

NOVELTY - Graphene nano-hybrid material comprises combination of double-electricity protein and graphene, which is highly stable in water at high concentration dispersion. USE - Graphene nano-hybrid material is used in polymer composite materials, gel materials, and phase change materials (claimed), and functional materials, and intelligent nano materials. ADVANTAGE - The graphene nano-hybrid material has double electric property, pH response, and good redispersibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene nano-hybrid material, which involves mixing and stripping electric double-electrode protein dispersion and graphite, and regulating quality of double electrically-protein dispersion and graphite ratio, pH value of mixed stripping time and casein, where the mass ratio of the electric doublet protein and graphite is 0.025:1 to 20:1.
