The invention discloses an orderly graphene conductive polyimide film and a preparation method thereof. The orderly graphene conductive polyimide film consists of a polyimide base layer, a conductive covering layer, and an orderly graphene outer layer; the preparation method of the orderly graphene conductive polyimide film comprises the steps: through polyimide-liquefied and cured polyimide film and pre-dispersed conductive coating, performing primary coating and amination to produce a conductive polyimide film, grinding to generate graphene oxide colloidal suspension, performing secondary coating and discharging to prepare the orderly graphene conductive polyimide film. The graphene oxide colloidal suspension is utilized for carrying out the secondary conductive coating liquid coating processing on the conductive polyimide film, so that the conductivity is greatly enhanced; the orderly graphene conductive polyimide film is manufactured by adopting cheap raw materials, so that the production cost can be lowered; and the preparation method is simple, and the production efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of preparation of ordered graphene conductive polyimide films, in particular to an ordered graphene conductive polyimide film and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional carbon atom crystal with a thickness of one atom, which is considered as the basic structural unit of fullerene, carbon nanotube (CNT) and graphite. In 2004, Ceim et al. peeled off a small amount of single-layer graphene from a high-crystalline graphite block by adhesive tape method, and studied its electrical properties, and found that it has special electronic properties, such as the quantum Hall effect. The high mobility of carriers can still be maintained, which has great potential in the development of new electronic components. In 2007, Ruoff of Northwestern University in the United States prepared a colloidal suspension of graphene oxide by ultrasonically exfoliating graphite oxide, a...
