NOVELTY - The utility model claims a low pressure graphene electrothermal film, comprising a base film, an electrode, a heating conductive coating, the base film is provided with an electrode: a bus bar and an inner electrode, the inner electrode is formed interdigital electrode by bus bar extending oppositely; and then uniformly coating or printing the graphene conductive coating for heating on the base film; the base film tightly fixes the conductive coating between the base film and the plastic sealing film through the hot-pressing plastic sealing film; The bus bar is connected with the positive electrode and the negative electrode of the power supply, so that the polarities of the adjacent inner electrodes are opposite. The utility model is set by the distance between the bus bar and the inner electrode, can adjust the resistance of the conductive coating between the two electrodes, so as to use the 5V to 36V safety the voltage supply, the electric heating film heating under the low voltage environment, the temperature can be designed in 80 degrees centigrade, which can be well practical.
