▎ 摘　　要

NOVELTY - Graphene is prepared by placing graphite oxide into polar organic solvent, ultrasonically treating for 2-5 hours for preparing suspension solution (0.01-10 g/liter), heating up the suspension solution for 4-24 hours until the suspension solution is black, partially or completely condensing, filtering the solution for removing polar organic solvent, dripping organic electrolyte solution into the filter cake and filtering for preparing black slurry, directly coating on a bridle body for use, or directly drying the filter cake for preparing the graphene material. USE - Method for preparing graphene via heating up organic solvent suspension solution of graphite oxide (claimed). ADVANTAGE - The method is simple in step and instrument, is easy in production in a large scale, and can obtain anhydrous graphene material with low cost and high conductivity.
