Large scale graphene

Boosting the production of graphene, and controlling and maintaining its unique properties, is a challenge yet to be solved yet, one of the barriers to the industrial production of graphene may be broken as a result of new research. Existing methods of producing high quality graphene/graphite oxides are generally accomplished by exfoliating graphite into flakes and oxidizing the graphite flakes with strong oxidizers under extreme conditions and require careful purification.
