NOVELTY - A graphene electrothermal film, comprising conductive carbon slurry on the printed film, the lattice-shaped film is provided with gap, the gap located in the conductive carbon slurry. the gap is one or any combination of more than two of any one of square, round, triangle. the film in the utility model is provided with a lattice-shaped gap, the gap located in conductive carbon slurry, when printing the conductive carbon paste, gap of the dot is not printed, that is, when the product works, conductive paste and film when it is heated, it can be expanded, and the lattice gap provides enough extension space is expanded, so as to improve the safety. and the film of authorities and conductive carbon slurry on it being broken or cut, the current can be obtained from the breaking or severing of the near past, without local current overlarge, caused the product local high temperature to affect the normal use of the product. The product has a high degree of safety.
