Description

technical field [0001] The invention relates to a nanocomposite conduction electric heating film and a preparation method thereof, belonging to the field of material technology. Background technique [0002] Electrothermal film is the abbreviation of a film that can generate heat after being energized. The core element is a layer of conductive heating material layer with electrodes installed at both ends. After adding voltage, the current passes through the conductive heating layer to form electric energy and thermal energy conversion. The electrothermal film is a material that can conduct infrared radiation and achieve low-temperature heating after being energized. It is generally printed on the substrate by using carbon crystal ink. Carbon crystal ink is also called far-infrared electrothermal ink, which is a crystal structure of carbon elements. , modified by short carbon fiber and then ball-milled to make microcrystalline particles, then add far-infrared emitter and othe...
