Title:
GRAPHENE FILM TRANSFER METHOD, AND METHOD FOR MANUFACTURING TRANSPARENT CONDUCTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2012/093443
Kind Code:
A1
Abstract:
[Problem] To provide a graphene film transfer method and method for manufacturing a transparent conductive film with excellent mass productivity that enables the transfer of a graphene film with good adhesiveness to a desired substrate and that can effectively prevent defects from appearing on the graphene film. [Solution] A second substrate (14) and one layer or multiple layers of a graphene film (12) formed on a first substrate (11) are bonded using an adhesive resin layer (13) in which the amount of volatile substance is less than 1% by weight. The thickness of the resin layer (13) is reduced by applying pressure to the first substrate (11) and the second substrate (14), and after the resin layer (13) has cured the first substrate (11) is removed.
