▎ 摘  要

NOVELTY - Preparation of three-dimensional graphene structure/high quality graphene involves subjecting raw material graphite to intercalation treatment, and intercalating into graphite layers to obtain graphite intercalation compound; and adding graphite intercalation compound into expansion agent, settling down for 1-48 hours, stirring for 15 minutes, adding swelling agent to graphite layers, decomposing interlayer, releasing gas, increasing graphene interlayer distance, separating graphene layers from each other, and forming three-dimensional graphene structure with high specific surface area. USE - Method for preparing three-dimensional graphene structure/high quality graphene used in high ratio surface area carbon aerogel skeleton, polymer, metal oxide, metal sulfide, nitride, energy storage composite material, conductive ink, and conductive film. ADVANTAGE - The structure has excellent electric performance and conductivity.
