We report an efficient and economical way for mass production of large-scale graphene films with high quality and uniformity. By using the designed scrolled copper-graphite structure, a continuous graphene film with typical area of 200 x 39 cm(2)could be obtained in 15 min, and the production rate of the graphene film and space utilization rate of the CVD reactor can reach 520 cm(2).min(-1)and 0.38 cm(-1).min(-1), respectively. Our method provides a guidance for the industrial production of graphene films, and may also accelerate its large-scale applications.
