▎ 摘　　要

NOVELTY - Producing low thickness graphene, comprises (a) preparing functional additive dispersion solution by dispersing functional additive for preventing reagglomeration in dispersion solvent, (b) adding graphite into the dispersion solution, and (c) passing the graphite-added dispersion solution through a high pressure cell. USE - The method is useful for producing low thickness graphene. ADVANTAGE - The method prevents re-agglomeration of graphene particles during or after exfoliation process, and solves problem in increase of graphene thickness due to occurrence of graphene defects and reaggregation in high concentration acid treatment. The low thickness graphene has hybrid structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for low thickness graphene produced by the above method.
