NOVELTY - Preparing graphene electrothermal film comprises sequentially coating release ink on the surface of the substrate to form release layer, coating graphene conductive ink to form a graphene conductive layer, and coating an adhesive to form a first adhesive layer, bonding the first fiber fabric with the first adhesive layer and peeling off the base material by hot pressing, coating an adhesive on the surface of the release layer away from the graphene conductive layer exposed after peeling off the base material to form second adhesive layer, and bonding the second fiber fabric to the second adhesive layer and performing to hot pressing operation. USE - The method is useful for preparing graphene electrothermal film. ADVANTAGE - The high-strength fiber fabric is the load-bearing matrix, and does not contain plastic materials for polyethylene terephthalate and polyimide, the graphene electrothermal film solves the problem of poor flexibility and comfort of the electric heating film in the prior art, and can also realize roll-to-roll large-scale production, and improves production efficiency.
