Abstract
An embodiment provides a Joule heating-based roll-to-roll graphene manufacturing method and a graphene manufacturing apparatus, by suppressing the stress concentration and deformation generated in a catalytic metal passing between a first roller part and a second roller part, stable roll-to-roll transfer for a synthesis area arranged so as to extend in a downward direction can be ensured for temperature compensation, and the synthesis area is transferred in a state of maintaining a concave shape toward a temperature compensation area without a cross section distorted in the longitudinal direction.
