Description

technical field [0001] The invention relates to an electric heating film, in particular to a graphene electric heating film and its preparation method and application. Background technique [0002] Graphene has very good thermal conductivity properties. The thermal conductivity of pure defect-free single-layer graphene is as high as 5300W / mK, which is the carbon material with the highest thermal conductivity so far, higher than single-walled carbon nanotubes (3500W / mK) and multi-walled carbon nanotubes (3000W / mK) . When it is used as a carrier, its thermal conductivity can also reach 600W / mK. Therefore, graphene has the potential to replace metals in the field of electrothermal films. At present, the graphene electrothermal film has the disadvantages of limited flexibility and damage after repeated folding. Therefore, the present invention provides a highly flexible graphene electrothermal film and its preparation method and application. Contents of the invention [0...
