what is graphene oxide

Graphene oxide (GO) is the oxidized form of graphene, which is a single-atomic-layered material formed by the oxidation of graphite. GO is a unique material that can be viewed as a single monomolecular layer of graphite with various oxygen-containing functionalities such as epoxides, alcohols, and carboxylic acids. Graphene oxide is easy to process since it is dispersible in water and other solvents, and it can be reduced to graphene by chemical methods. One of the main advantages of graphene oxide is that it is dispersible in water, making it possible to use solution-based processes. However, due to the oxygen in its lattice, graphene oxide is not conductive. Once reduced graphene oxide has been produced, there are numerous ways that can be used to functionalize it, enhancing the properties of the rGO film to be used in various applications.
