NOVELTY - A high stability graphene dispersion comprises 0.1-10 %mass graphene, 0.1-10 %mass dispersant, and 80-99.8 %mass dispersing medium. The dispersant is an organic compound containing a benzene ring group, and forms a ( pi )-( pi ) bond interaction with graphene. USE - High stability graphene dispersion. ADVANTAGE - The graphene dispersion has high stability, stable dispersion without agglomeration settlement for a long time, and high concentration of graphene, and is prepared by simple and economical process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of high stability graphene dispersion, which involves adding dispersant to dispersing medium in proportion to form a dispersion, mixing graphene with the dispersion in proportion, and dispersing for 0.5-1 hour to obtain graphene dispersion solution, and drying the graphene dispersion solution when the dispersion medium does not contain polymer resin.
