NOVELTY - A graphene-protein-derived carbon super-capacitor material preparing method involves mixing water soluble proteins and graphene oxide to obtain a protein and graphene oxide mixed solution, subjecting the mixed solution to reduction reaction to obtain water soluble protein graphene oxide. The water soluble protein graphene oxide is stirred with pore-forming agent and subjected to dying process under vacuum, film casting and carbonization treatment to obtain porous material, followed by washing the material with water and ethanol in a vacuum oven and drying to obtain finished product. USE - Method for preparing graphene-protein-derived carbon super-capacitor material that is utilized for electric cars, wind power generation and solar energy generation. ADVANTAGE - The method enables preparing graphene-protein-derived carbon super-capacitor material with high current density, better electrical conductivity and ultra-high specific capacity. DETAILED DESCRIPTION - A graphene-protein-derived carbon super-capacitor material preparing method involves mixing 0.5-20% water soluble proteins and 0.01-5% graphene oxide to ratio of 1:50-50:1 with pH of 6-14 to obtain a protein and graphene oxide mixed solution, subjecting the mixed solution to reduction reaction with reducing agent at 30-250 degrees C for 0.5-2 hours to obtain water soluble protein graphene oxide. The water soluble protein graphene oxide is stirred with pore-forming agent and subjected to dying process under vacuum, film casting and carbonization treatment under nitrogen or argon gas atmosphere to speed of 5-30 rpm at 500-900 degrees C for 1-5 hours to obtain porous graphene protein-derived material, followed by washing the material with water and ethanol in a vacuum oven at 30-50 degrees C and drying for 3-8 hours to obtain porous graphene protein-derived carbon composite material.
