▎ 摘　　要

NOVELTY - The synthesis method of graphene material involves uniformly dispersing graphite oxide-alcoholic dispersion and encapsulated powder materials in alcohol solvent constituting mixed system, transferring mixed system to reactor, sealing and reacting. The alcohol is glycerol, ethylene glycol, ethanol, and/or propylene glycol. The alcohol solvent is isopropanol, isobutanol, n-butanol, and/or n-propanol. USE - Synthesis of graphene material for protective packaging. ADVANTAGE - The method enables simple, convenient and environmentally-friendly synthesis of graphene material with excellent elasticity, stability and protective function, and high reproducibility. DETAILED DESCRIPTION - The synthesis method of graphene material involves uniformly dispersing graphite oxide-alcoholic dispersion and encapsulated powder materials in alcohol solvent constituting mixed system, transferring mixed system to reactor, sealing and reacting. The mass ratio of graphite oxide-alcoholic dispersion and encapsulated powder materials is 4:1-1:20. The concentration of graphite oxide-alcoholic dispersion is less than or equal to 20 mg/ml. The encapsulated powder material is element, oxide or sulfide. The alcohol is glycerol, ethylene glycol, ethanol, and/or propylene glycol. The alcohol solvent is isopropanol, isobutanol, n-butanol, and/or n-propanol.
