NOVELTY - A graphene aerogel with high strength and high resilience is prepared by adding graphite oxide in alkaline solution, mechanically stirring for 0.5-6 hours to prepare 2-10 mg/ml graphene oxide solution with good dispersibility, adjusting temperature to freezing point of water to boiling point, adding reducing agent, magnetically stirring for 0.5-2 hours, pouring into reaction kettle and sealing, putting into oven for hydrothermal reaction to obtain graphene hydrogel, alcohol washing using 2-20% ethanol solution, and freeze-drying. USE - The method is used for preparing graphene aerogel with high strength and high resilience. ADVANTAGE - The product has low density, high mechanical strength, uniform crosslinking hole, high conductivity and good rebound resilience.
