▎ 摘　　要

NOVELTY - Manufacturing graphene comprises crushing graphene nanoplate with expanded graphite or exfoliated structure using blender, dispersing crushed graphene nanoplate in a solvent such that solvent is inserted between the layers of graphene nanoplate, performing ultrasonic treatment, centrifuging the obtained dispersion and collecting supernatant, filtering the supernatant and drying. USE - Graphene is useful in composite material and as filler for transparent electrode. ADVANTAGE - The method controls the number of layers in the produced graphene to less than or equal to 10, does not use sulfuric acid as solvent and is cost-efficient.
