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. Problems associated with large-scale pattern growth of graphene constitute one of the main obstacles to using this material in device applications recently, macroscopic-scale graphene films were prepared by two-dimensional assembly of graphene sheets chemically derived from graphite crystals and graphene oxides.

Imagine you are a company like spacex a material like graphene that is 200 times stronger than steel will allow you [. One of the greatest challenges being faced today in commercializing graphene is how to produce high quality material, on a large scale at low cost, and in a reproducible manner the major hurdle in manufacturing graphene on an industrial scale is the process complexity and the associated high cost of its production, which results in expensive. Scaling up the production of graphene-based materials is potentially dangerous, because graphene oxide has been proven to possess a fire hazard researchers solve graphene's flammability problem, open door to large-scale production.
