▎ 摘  要

NOVELTY - Honeycomb structure of graphene airgel ball preparation involves mixing 1 pts. wt. graphene oxide, 20-50 pts. wt. water and 0.1-1 pts. wt. alkaline substance in a reactor. The obtained mixture is stirred. The obtained stirred mixture is extruded. The obtained mixture is coagulated on coagulating bath. The obtained product is soaked in a 20-50 pts. wt. water. The obtained mixture is reduced in an oventank at 60-95 degrees C for 10 hours. The obtained mixture is frozen for 1-2 hours. The obtained mixture is soaked in a solvent. The obtained soaked mixture is washed at 60 degrees C. USE - Method for preparing honeycomb structure of graphene airgel ball (claimed). ADVANTAGE - The method enables to prepare honeycomb structure of graphene airgel ball that has excellent electrical conductivity, mechanical property and resilience.
