The invention relates to a reel-to-reel manufacturing method for upright graphene. Micro structures with a depth-to-width ratio are continuously prepared by utilizing a roller imprinting technology; agraphene flowing directed assembling behavior is modulated by utilizing the micro structures; an effect that an assembling mode of a graphene slice layer is changed into an upright directed assembling from horizontal layered stacking is achieved; and reel-to-reel large-scale preparation of the upright graphene is implemented. The reel-to-reel manufacturing method disclosed by the invention can beused for a sandwich structural supercapacitor; according to the reel-to-reel manufacturing method, an electric field direction is parallel to an orientation of the slice layer, a rapid ion channel isformed, a problem of a restrictive relation between a large film thickness and a high load of the graphene supercapacitor and an ion transport distance is solved, and meanwhile, limitation of an interdigital structural micro supercapacitor to load capacity is broken through; and the reel-to-reel manufacturing method is applicable to a chip radiator, heat can be led to be directionally conducted along a direction with high heat conductivity, high-efficiency heat dissipation in a limited space is implemented, and the reel-to-reel manufacturing method has important significance for manufacturingintegrated chips such as a CPU and the like.
