Graphene films are thin layers made from a single layer of graphene, a remarkable material composed of carbon atoms arranged in a two-dimensional honeycomb lattice. Known for its exceptional strength, electrical conductivity, and flexibility, graphene films have potential applications in various fields, including electronics, energy storage, and sensors. These films can be produced through several methods, such as chemical vapor deposition and liquid-phase exfoliation. Their unique properties make them ideal for use in advanced technologies, including transparent conductive coatings for displays and touchscreens, as well as components in supercapacitors and batteries.
