▎ 摘　　要

NOVELTY - The preparation method of graphene involves dissolving intercalating agent in deionized water and then uniformly mixing to obtain intercalant solution, adding graphite powder to the intercalant solution and then uniformly mixing to obtain 10-30 %mass graphite powder suspension, processing the graphite powder suspension and then filtering, washing the filtrate using deionized water and then drying under vacuum, and removing moisture. The intercalating agent is water-soluble polymer. USE - The method is useful for preparation of graphene (claimed). ADVANTAGE - The method enables preparation of graphene with high efficiency and large size.
