摘要
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 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.
