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 × 39 cm2 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 cm2⋅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.
