Method for producing multilayer structure, multilayer structure and electronic device

Abstract

A multilayer structure is produced by bonding one or more graphene layers (12), which are formed on a first substrate (11), and a second substrate (13) with each other by a roll-to-roll method by means of an adhesive layer (14) that is formed of a delayed ultraviolet-curable resin. A metal foil is used as the first substrate (11), while a transparent substrate is used as the second substrate (13).

Description

technical field [0001] The present disclosure relates to a manufacturing method of a laminated structure, a laminated structure, and an electronic device, and is preferably applied to, for example, transparent conductive films used in displays and touch panels, and various electronic devices respectively including the transparent conductive films. Background technique [0002] Graphene including carbon atoms of single-layer graphite is expected as a transparent conductive material or a wiring material due to its high conductivity. In particular, graphene synthesized by a thermal CVD method attracts attention because a film can be formed over a large area while controlling the number of layers. [0003] In the synthesis method of graphene by thermal CVD method, graphene is formed on a metal catalyst substrate, usually on a copper foil. Therefore, the formed graphene needs to be transferred from the metal catalyst substrate to the desired substrate. [0004] As a transfer me...

Problems solved by technology

However, thermosetting resins have the following problems: (1) Curing requires prolonged temperature rise, and (2) Large-scale equipment is required because a solvent drying process is usually required
