Title:
METHOD OF MANUFACTURING GRAPHENE FILM AND GRAPHENE FILM MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2014/126298
Kind Code:
A1
Abstract:
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.
