NOVELTY - Preparing graphene material using ball milling comprises (i) mixing graphite carbon, alkylated six-membered aromatic ring or fused ring polyether nonionic surfactant and deionized water in a ball mill according to ratio of 1:2-1:15, and ball milling for 5-30 hours under ball milling speed of 200-500 rotation/minute; and (ii) adding the product obtained in the step (i) into deionized water, centrifuging for 10-30 minutes under centrifugal speed of 3000-8000 rotation/minute to obtain black upper layer colloidal suspension, and obtaining aqueous graphene solution with different concentrations. USE - The method is useful for preparing graphene material using ball milling (claimed). ADVANTAGE - The method: utilizes the ball mill, which is simple, easy to operate and safe; is simple; has mild reaction condition and large yield. The graphene material is environmentally friendly.
