JOULE HEATING-BASED ROLL-TO-ROLL GRAPHENE MANUFACTURING METHOD AND GRAPHENE MANUFACTURING APPARATUS

WIPO Patent Application WO/2023/128398

A1

The present invention provides a Joule heating-based roll-to-roll graphene manufacturing method and a graphene manufacturing apparatus, in which, 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. To this end, in the present invention, a Joule heating-based roll-to-roll graphene manufacturing apparatus including a first roller part and a second roller part for Joule-heating a catalytic metal is used, and, for temperature compensation, while passing between the first roller part and the second roller part, provided is a synthesis area arranged so as to extend in a downward direction due to its own weight, wherein 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.
