METHOD OF OBTAINING GRAPHENE

摘要

According to an aspect of an exemplary embodiment, there is provided a method of obtaining graphene, the method comprising: preparing a graphene forming structure of which a first graphene is formed on one surface and a second graphene is formed on another surface, and that comprises at least one metal catalyst member; disposing a first carrier and a second carrier on the first graphene and the second graphene, respectively; and removing the metal catalyst member by applying an etchant to a side surface of the graphene forming structure while winding up the first carrier and the second carrier by respectively rotating a pair of rolls formed to face each other.
