GRAPHENE FILM AND MANUFACTURING METHOD THEREOF

摘要

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.

1. A graphene film manufacturing method, comprising the following steps:
(a) mixing a polymer solution with graphene flakes to form liquid graphene; (b) placing the liquid graphene, in batches, in a stirring device to allow the liquid graphene to be stirred by the stirring device; (c) coating the stirred liquid graphene on a substrate to form a graphene coating layer so that the graphene coating layer is supported on and carried by the substrate; and (d) using a drying device to remove liquid from the polymer solution so as to form a graphene film having a fixed shape.
