Abstract

In various embodiments, the present invention provides electrically conductive and radio frequency (RF) transparent films that include a graphene layer and a substrate associated with the graphene layer. In some embodiments, the graphene layer has a thickness of less than about 100 nm. In some embodiments, the graphene layer of the film is adhesively associated with the substrate. In more specific embodiments, the graphene layer includes graphene nanoribbons that are in a disordered network. Further embodiments of the present invention pertain to methods of making the aforementioned electrically conductive and RF transparent films. Such methods generally include associating a graphene composition with a substrate to form a graphene layer on a surface of the substrate.
