▎ 摘  要

NOVELTY - The electrically conductive and radio frequency transparent film comprises a graphene layer, and a substrate associated with the graphene layer. The graphene layer consists of functionalized graphene nanoribbons, pristine graphene nanonbbons, doped graphene nanoribbons, pristine graphene, doped graphene, graphene oxide, reduced graphene oxide, chemically converted graphene, split carbon nanotubes, and/or mixtures of graphene nanoribbons and carbon nanotubes. The graphene layer is adhesively associated with the substrate, and positioned on a top surface of the substrate. USE - The electrically conductive and radio frequency transparent film is useful in anti-icing or de-icing heat circuits, as coating for de-icing or anti-icing applications including de-icing of antennas, radomes or aircraft structures such as wing edges, as anti-icing or de-icing circuits in ships, aircraft, spacecraft, boats and bridges, and as components of aircraft and helicopter composites to provide heating for de-icing. ADVANTAGE - The electrically conductive and radio frequency thin transparent film exhibits high conductivity and transparency, low resistance, good compactness, uniform coverage of large surfaces, improved durability and excellent resistance to oxidation, is less expensive, and is capable of withstanding at hostile environments including salt water, strong winds, snow, ice, gun blasts, dust and wide temperature variations. DETAILED DESCRIPTION - The electrically conductive and radio frequency transparent film comprises a graphene layer, and a substrate associated with the graphene layer. The graphene layer consists of functionalized graphene nanoribbons, pristine graphene nanonbbons, doped graphene nanoribbons, pristine graphene, doped graphene, graphene oxide, reduced graphene oxide, chemically converted graphene, split carbon nanotubes, and/or mixtures of graphene nanoribbons and carbon nanotubes. The graphene layer is adhesively associated with the substrate, and positioned on a top surface of the substrate. The graphene nanoribbons are: provided in contiguous sheets; disordered on the substrate; aligned on the substrate; and derived from split multiwalled carbon nanotubes. The substrate consists of glass, quartz, boron nitride, alumina, silicon, plastics and/or polymers, and comprises an adhesive layer, which is positioned between the substrate and the graphene nanoribbon layer. The film has a radio frequency transparency of 0.1-18 GHz. The graphene layer has a thickness of 50-100 nm. An INDEPENDENT CLAIM is included for a method of making an electrically conductive and radio frequency transparent film. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a photograph of a transparent graphene nanoribbon film.
