Abstract

The application discloses a single-sided transmission graphene film. The single-sided transmission graphene film comprises a body, wherein the body comprises a first substrate layer, a second substrate layer, a heating layer and a reflective layer; the heating layer is arranged between the first substrate layer and the second substrate layer; the reflective layer is arranged on one side, deviatingfrom the heating layer, of the second substrate layer and is used for reflecting far infrared light emitted by the heating layer after electrifying. According to the application, the technical problem that the graphene film has no function of reflecting far infrared light and needs additional far infrared reflector in the actual application of a product, so that the thickness of the film is increased is solved.

Description

technical field [0001] The present application relates to the field of graphene preparation, in particular, to a single-sided transmission graphene membrane. Background technique [0002] Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. [0003] 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, the thermal conductivity can reach 600W / mK. In addition, the ballistic thermal conductivity of graphene can lower the lower limit of the ballistic thermal conductivity of carbo...
