NOVELTY - Preparation of latticed composite transparent heating component involves (i) preparing a latticed nickel-based metal transparent conductive material on a high-temperature-resistant transparent substrate by metal deposition-etching method, (ii) coating a carbon nanotube film on the conductive material to fill the opening area of the metal mesh of the conductive material to form a metal-nanocarbon conductive film, (iii) forming a graphene film on the conductive material by low-pressure high-temperature solid-state carbon source chemical vapor deposition method to obtain a metal-graphene/carbon nanotube composite transparent conductive film, and (iv) encapsulating the conductive film. USE - Preparation of latticed composite transparent heating component used for high-temperature-resistant electrothermal device and in medical application. ADVANTAGE - The preparation ensures the conductive characteristic of conductive material, satisfies the different electric heating device driving voltage requirement. The introduction of carbon-based material ensures efficient far infrared radiation, which is good for cooking, baking kitchen appliance design. At the same time, the method can realize electric heating devices design with different transmittance according to the requirement. Because the whole conductive film is the micron metal grid structure based on the metal deposition-etching method, the metal-graphene-carbon nano-tube composite transparent conductive films can be used as the heating material, on the basis, preparation is a complete high temperature resistant transparent heating body.
