Design overview of synthesis and transfer processes for graphene film. a The CVD growth of graphene on Cu foil; CH4 was using as the carbon source. b Illustration of the first transfer process of bubbling off graphene from Cu substrate; PET coated with heat release adhesive (HRA) was used as support layer. The electrolyte was NaOH aqueous solution, Pt was used as anode, and PET/HRA/graphene/Cu foil was cathode. c, d Illustration of secondary-transferring graphene electrode. Drip and spin coat the UV-curable polymer NOA63 on graphene/HRA/PET substrate, then solidify NOA63 film and left it off from graphene/HRA/PET
