According to an aspect of the present invention, there is provided a method of manufacturing a graphene film, the method including: preparing a catalyst metal having at least a surface on which graphene is formed; forming a support layer on the graphene; and isolating the graphene and the support layer from the catalyst metal by dipping the catalyst metal in an electrolytic solution perpendicularly to a liquid surface of the electrolytic solution when a voltage is applied to the catalyst metal.

Method of manufacturing graphene film and graphene film manufactured thereby

A method of manufacturing graphene, the method including: preparing a carrier member on which the graphene is formed on one surface thereof; exposing the graphene to dopant vapor to dope the graphene; transferring the doped graphene onto a target member; and removing the carrier member.

Method for manufacturing graphene layer

A method of fabricating multi-layered graphene includes disposing a first graphene layer on a carrier; disposing at least one second graphene layer on the first graphene layer to form a graphene sheet disposed on the carrier; and transferring the graphene sheet disposed on the carrier onto a substrate, wherein each of the graphene layers which constitute the graphene sheet has at least one damaged region, and the at least one damaged region of each of the graphene layers contacts at least one of non-damaged regions of a graphene layer or graphene layers, of the graphene layers, contacting the each of the graphene layers.

Multi-layered graphene sheet and method of fabricating the same

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.

Method and apparatus for transferring graphene

Provided is a method of post treating graphene including providing graphene on a metal thin film, providing a carrier on the graphene, hardening the carrier, and removing the metal thin film from the graphene.
