▎ 摘  要

NOVELTY - The low temperature thermoforming method for three-dimensional graphene material involves preparing graphene oxide solution having concentration of 1-20 mg/ml by oxidative stripping process, mixing graphene oxide solution with reductive polymerizable monomer to obtain mixed solution, reacting mixture at 60-80 degrees C for 2-12 hours, cooling at room temperature to obtain three-dimensional graphene assembly, and freeze-drying the three-dimensional graphene assembly. The volume fraction of reductive polymerized monomer in mixed solution is 0.5-5%. USE - Low temperature thermoforming method for three-dimensional graphene material used in super capacitor electrode material or lithium ion battery electrode material (all claimed). ADVANTAGE - The method enables thermoforming process of three-dimensional graphene material by simple and easy process, and controls the degree of reduction of graphene oxide by selecting and optimizing the key reactants. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) three-dimensional graphene material; and (2) usage of three-dimensional graphene material in super capacitor electrode material or lithium ion battery electrode material.
