Graphene oxide (GO) is a single-atom layered material, produced by the strong oxidation of graphite, which is a cheap and abundant material. Graphene oxide is an oxidized form of graphene, terminated with oxygen-containing groups. GO is dispersible in water. Reduction of GO leads to the formation of graphene. For this many methods ranging from photochemical reduction (e.g. using the flash of a photo-camera) to chemical reduction can be employed. The reduction of Graphene oxide boosts its electrical conductivity making it possible to employ this material for the production of transparent conductive films for electronics, touch screens, in chemical sensors, solar cells, batteries etc. The possibility to easily assemble thin films from the solutions of GO opens ways for cost-effective and massive applications.
Graphene Oxide has a high specific surface area (SSA), which makes this material perfectly fit for the use in batteries and capacitors. Dry graphene oxide and its dispersions can be easily mixed with different polymers and other materials to enhance their mechanical properties like tensile strength, elasticity, conductivity etc.
