The invention discloses a high molecular electric heating film and the application thereof. The high molecular electric heating film is prepared by coating the high molecular conducting paint, compounded by bridging and selective graft technology, uniformly on the base material with an electrode and an insulation process. The high molecular electric heating film achieves long useful life, high thermal efficiency and high safety; it can be applied in building heating, pipeline and tank mix heating, melting snow and ice, agricultural seeding, physical therapy and health protection, especially in the fields of floor heating, satellite antenna snow melting, health caring environment, health caring clothes and so on. Application in the floor heating can solve the problems of weathering resistance, electric safety, product applicability, local overheating, leakage current, electromagnetic radiation; application in satellite antenna snow melting can solve the problem that the electromagnetic radiation disturbs satellite signals.
