Abstract：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 $200 \times 39$ 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}$$\cdot$min$^{-1}$ and 0.38 cm$^{-1}$$\cdot$min$^{-1}$, respectively. Our method provides a guidance for the industrial production of graphene films, and may also accelerate its large-scale applications.
