Graphene has the characteristics of high thermal conductivity, extremely fast conductivity, high barrier, ultra-thin performance, strong magnetism, high strength, high thermal stability, complete transparency and so on. In short, it is harder than diamond and lower than silver in resistance. It has a high conductivity and thermal conductivity, and is almost completely transparent, as soft as paper. When the electrodes at both ends of the graphene heating film are energized, the carbon molecules in the electric heating film produce phonons, ions and electrons in the resistance, and the generated carbon molecules generate heat energy by friction and collision between them. Heat energy is evenly radiated in a planar manner by controlling the far-infrared ray with a wavelength of 5-14 microns, which can be well absorbed by the human body. The total conversion rate of effective electric energy is more than 99%. At the same time, coupled with the superconductivity of special graphene materials, it can ensure the stability of heating performance. In other words, graphene can be used as a carrier to convert electrical energy into heat energy, and the efficiency of this conversion is higher than that of commercially available materials. Compared with the traditional resistance heating, graphene heating is safer and will not break down after power failure. Even if part of it is damaged, it will not affect the overall work.
