Graphene heating slurry, graphene heating film prepared from graphene heating slurry and preparation method of graphene heating film

The invention discloses graphene heating slurry, a graphene heating film prepared from the graphene heating slurry and a preparation method of the graphene heating film. The graphene heating slurry comprises modified graphene, a defoaming agent, a flame retardant and a solvent, the modified graphene is prepared by reacting a fluorocarbon surfactant with graphene oxide; the fluorocarbon surfactant has a structure as shown in the following formula A. According to the graphene heating slurry and the graphene heating film prepared from the graphene heating slurry provided by the invention, by adding the modified graphene, the dispersity of the graphene can be enhanced, the problem that the graphene is easy to agglomerate is effectively avoided, and the thermal stability of the slurry can be improved, so that the prepared graphene heating film is high in conductivity uniformity and uniform in surface electric heating temperature distribution; the thermal stability is high, and the electric heating performance is h
