Figure a) Large graphene coupons on Cu foil. b) Schematic of the membrane module. c) The evolution of the membrane area from 1 cm2 to 5 cm2 and to 50 cm2. d) A large-area graphene coupon produced by the novel process described above. The ruler shows a graphene coupon successfully transferred on a high-flux porous support (PES). The coupon size is larger than 11 cm in size with an area higher than 50 cm2, which is about 50 times larger than the state-of-the-art.
