Abstract
Provided are method and apparatus for transferring graphene. The graphene transferring method includes: a graphene synthesizing operation comprising forming at least one layer of graphene on at least one surface of a catalyst metal film; a substrate film attaching operation comprising contacting an adhesive first surface of the substrate film to the at least one layer of graphene and compressing the catalyst metal film and the substrate film by using a first roller; and a substrate film separating operation comprising separating the substrate film from the catalyst metal film such that the at least one layer of graphene is separated from the catalyst metal film together with the substrate film.
