  • Publication number: 20170096342
    Abstract: A graphene film and a manufacturing method thereof are disclosed. A polymer solution and graphene flakes (such as graphene powder) are mixed to form liquid graphene. The liquid graphene is disposed, in batches, into a stirring device to be stirred uniformly by the stirring device. The stirred liquid graphene is coated on a substrate (such as a paper material) to form a graphene coating layer supported on the substrate. A drying device is used to remove liquid from the polymer solution. As such, the graphene flakes having a weak bonding force is first process to form liquid graphene, which is uniformly coated on a substrate to form a graphene film having a fixed shape and strong bonding force thereby integrally bonded to the substrate as a unitary structure. The graphene film has a structure in which the graphene flakes are stacked in the same direction to form a laminate.
