Abstract

The invention discloses a double-side coated conducting film and a preparation method thereof. The double-side coated conducting film includes a film body, wherein the film body includes a base film,a graphene layer on both sides of the base film, and a sealant layer on both sides of the graphene layer; the base film can be prepared into a conducting film by a film processing device; and the filmprocessing device includes a film processing assembly, a hot press roll set and a cold press roll set; the film processing assembly comprises successively connected smooth rolling roll set, rough rolling roll set, coating roll set, graphene nozzle set, and ultraviolet laser emitter set. The preparation method of the double-side coated conducting film is simple in the process, satisfies the requirements of products with high adhesion requirements, enables the film body to be compact and strong through two or more times of rolling, and can effectively prevent the coated glue and the sprayed conductive powder from falling off and greatly improve the conductive performance of the conducting film through two or more times of coating the glue by means of the coating roll set, two or more timesof spraying conductive powder by means of the graphene nozzles, and two or more times of laser drying.

Description

technical field [0001] The invention relates to the field of conductive films, in particular to a double-sided coated conductive film and a preparation method thereof. Background technique [0002] A conductive film is a thin film having a conductive function. As a material for forming a conductive circuit on a substrate, conductive paints (sometimes called conductive pastes, conductive inks, etc.) containing conductive fillers such as silver powder and copper powder are known. for practical purposes. Generally, after the conductive paint is coated on the substrate by printing and other methods, the conductive film is made by sintering. [0003] Graphene is a new type of two-dimensional carbon material with a honeycomb structure composed of a single layer of carbon atoms. Graphene has excellent electrical conductivity, the electrical conductivity is 1.6 times that of copper; graphene has excellent transmittance to near-infrared, visible light and ultraviolet light, and the...
