NOVELTY - Manufacturing large-size single-layer graphene film comprises adhering small-size single-layer graphene sheet to substrate by using a viscous substrate, covering glue at the position of the material, and the single-layer graphene sheet cannot be adhering again, so as to ensuring that surface of the substrate is basically a single-layer graphene sheet, with a maximum of two layers in individual areas, the single-layer graphene adhered to the surface of the substrate is fused together and finally peeling off from substrate to form a complete large-size single-layer graphene film. USE - The method is useful for manufacturing large-size single-layer graphene film.
