▎ 摘 要
NOVELTY - Preparation of three-dimensional graphene foam material comprises mixing carbon source and pore-forming auxiliary agent, heating in presence of protective atmosphere to more than 950 degrees C, conducting thermal insulation reaction, and cooling to room temperature. The carbon source is organic matter. The pore-forming auxiliary agent is zinc metal powder or zinc sulfur compound powder. USE - The method is used for preparing three-dimensional graphene foam material (claimed). ADVANTAGE - The material has full-connected network structure, strong pore-forming ability, high quality, low cost, high specific surface area, low resistance, and does not have any solid rib, particle and other non-film appearance.
