[0072] The preparation method is as follows:
[0073] (1) Preparation of graphene heating film:
[0074] According to the method commonly used in public information, firstly mix 90 parts of polymer film-forming resin vinyl resin, 10 parts of diluent absolute ethanol, 10 parts of graphene, and 0.2 parts of sodium dodecyl benzene sulfonate as auxiliary agent, and mix them to obtain graphite. Ene resin mixture (graphene needs to be dispersed before use, the dispersion method is ultrasonic dispersion in absolute ethanol for 30 minutes), and then the graphene conductive is formed on the polyimide carrier by printing, spraying or coating After drying, the graphene conductive layer is obtained. An electrode is placed on the edge of the graphene layer, and then a polyimide insulating protective film with adhesive is attached to the graphene layer to form a graphene electric heating film .
