NOVELTY - Three-dimensional integral graphene aerogel-polyimine composite material is a whole block. Polyimine is polymerized into polyimine in situ in the pores of graphene aerogel. Polyimine enters the pores of the monolithic graphene aerogel from the solution by monomer penetration. USE - Three-dimensional integral graphene aerogel-polyimine composite material. ADVANTAGE - The three-dimensional integral graphene aerogel-polyimine composite material has good mechanical properties, excellent electrical conductivity and porous properties of graphene aerogel and the repairability and recovery performance of polyimine, and the overall performance is excellent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing three-dimensional integral graphene aerogel-polyimine composite material, which involves: (A) adding the dialdehyde compound to the organic solvent, then adding the amine source and the cross-linking agent, and obtaining a prepolymerized solution after being completely dispersed by magnetic stirring, where molar ratio of the dialdehyde compound, the amine source, and the crosslinking agent is 25-35:4-14:14, and the amine source and the crosslinking agent are different substances; (B) preparing bulk graphene aerogel, where average density of the graphite oxide dispersion is 5-12 mg/ml, the reducing agent is diethylene triamine, and the mass ratio of the reducing agent to graphene oxide is 1:9; (C) putting graphene aerogel into the uniformly dispersed polyimine monomer solution and letting stand for immersion until a white gel appears on the surface of the graphene aerogel, and then take it out; (D) using a gradient heating method to process the aerogel, from room temperature to 60-80 degrees C; (E) putting at room temperature for 0.5-3 h, move it to an oven and keep it at 30-50 degrees C for 0.5-3 h; and (F) increasing temperature to 60-80 degrees C, and the temperature is kept for 1-4 h to obtain the composite material.
