Abstract

A method for transferring graphene according to an exemplary embodiment of the present invention includes a process of transferring graphene of a metal sheet onto a thermal release film in each vacuum chamber and a process of transferring the graphene of the thermal release film onto a base material substrate. According to the method for transferring graphene, adhesion is increased by removing bubbles or foreign substances at the time of transferring the graphene to prevent separation of the graphene at the time of etching a metal substrate and enhance an adhesive quality state of the graphene on a target substrate.
