NOVELTY - The method involves using lift-off method on the high-temperature resistant transparent substrate to prepare a grid-shaped nickel-based metal transparent conductive material. A carbon nanotube film is introduced by coating on the basis of the nickel-based metal-transparent material obtained. The carbon nanofiber film is filled with a metal grid opening area to form a metal-nano-carbon conductive film. The low-pressure high temperature solid carbon source chemical vapor deposition method is used to prepare the graphene film on the nickel metal transparent material on the preparation graphene film to obtain the metal-graphene/carbon graphene-tube composite transparent film. The packaging process is used to obtain a graphene composite heating body. USE - Preparation method for composite heating graphene. ADVANTAGE - The method enables realizing electric heating device design with different transmittance according to the requirement, solves the problem that the traditional high temperature electric heating devices only adopts non-transparent material, and greatly expands the application direction of the electric heating. The metal-graphene-carbon nano-tube composite transparent conductive film as the heating material, on the one hand, it ensures conductive characteristic of the conductive material, it can satisfy the different electric device driving voltage requirement. The introduction of carbon-based material ensures efficient far infrared radiation, which is good for cooking, baking kitchen appliance design.
