NOVELTY - Preparation of three-dimensional graphene macroscopic material involves dissolving graphene oxide powder in organic solution to obtain graphene oxide organic solution (A), placing the reaction solution (A) in a reaction kettle, reacting at 100-400 degrees C for 0.5-12 hours by solvothermal method, cleaning and drying. The drying is freezing at -18 degrees C to -30 degrees C and drying at 80-120 degrees C. USE - Preparation of three-dimensional graphene macroscopic material (claimed).
