▎ 摘 要
NOVELTY - A graphene oxygen-releasing electrothermal film has a carbon fiber heating component, a negative oxygen ion generating material, a hot melt adhesive, an insulating layer and a protective layer. The two surfaces of the carbon fiber heating component are adhered to the insulating layer through the hot melt adhesive. The surfaces of the insulating layer away from the carbon fiber heating component are respectively connected to the negative oxygen ion generating material. The surface of the negative oxygen ion generating material away from the carbon fiber heating component is connected with the protective layer. The two short sides of the carbon fiber heating component are connected with a conductor. The two conductors connected by the carbon fiber heating component are respectively connected with a conductive wire. The two conductive wires connected to the conductors are respectively connected to a power controller. USE - Electrothermal film is useful for releasing graphene and oxygen. ADVANTAGE - The graphene oxygen-releasing electrothermal film has high electrothermal conversion rate of 98% and thermal energy, reduces waste of electricity, is not easy to bulge during use, and can be prepared with high yield in easy manner. The negative oxygen ion generating material releases negative oxygen ions, can effectively remove formaldehyde, bacteria and other microorganisms in the air, and enhances human immunity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparation of graphene oxygen-releasing electrothermal film.
