Macromolecular conductive film for electric automobile, production equipment and preparation method of polymer conductive film for electric automobile

Abstract

The invention relates to the technical field of automobile accessories, in particular to a polymer conductive film. The conductive film comprises a base film, a bottom coating, a conductive layer anda protective coating, wherein the bottom coating is sprayed on the top of the base film; the conductive layer is sprayed on the top of the bottom coating; the protective coating is sprayed on the topof the conductive layer; the base film is prepared from one or more of polyethylene, polypropylene, polyethylene glycol terephthalate, polytrimethylene terephthalate, polyimide, polyamideimide, polyether sulfone, polyether-ether-ketone, polycarbonate, polyarylester, cellulose propionate and polyvinyl chloride. The invention further discloses production equipment and a preparation method of the polymer conductive film for an electric automobile. The conductive film is prepared on glass through vacuum magnetron sputtering and ultrasonic high-temperature vaporization, the production equipment issimple in structure and low in cost, automatic control can be realized, the operation is simple and convenient, and the prepared conductive film is uniform in structure and stable in performance.

Description

technical field [0001] The invention relates to the technical field of automotive supplies, in particular to a polymer conductive film for electric vehicles, production equipment and a preparation method. Background technique [0002] The conductive film is a thin film with conductive function. The charge carriers of the conductive film are scattered by the surface and interface during the transport process. When the thickness of the film can be compared with the free path of electrons, the influence on the surface and interface will be This phenomenon is called the size effect of the film, which is equivalent to the reduction of the free path of the carriers, so the conductivity of the film is smaller than that of the bulk of the same material. [0003] Conductive films can be applied to touch panels, rearview mirrors, and rear windshields of electric vehicles. However, the existing conductive film production equipment has complex structures, high costs, troublesome operati...
