Description

 

Graphene Oxide is one of those materials - it is a single-atomic layered material, made by the powerful oxidation of graphite, which is cheap and abundant. Graphene oxide is an oxidized form of graphene, laced with oxygen-containing groups. It is considered easy to process since it is dispersible in water (and other solvents), and it can even be used to make graphene. Graphene oxide is not a good conductor, but processes exist to augment its properties. It is commonly sold in powder form, dispersed, or as a coating on substrates. Graphene oxide is synthesized using four basic methods: Staudenmaier, Hofmann, Brodie and Hummers. Many variations of these methods exist, with improvements constantly being explored to achieve better results and cheaper processes. The effectiveness of an oxidation process is often evaluated by the carbon/oxygen ratios of the graphene oxide. Graphene Oxide has a high surface area, and so it can be fit for use as electrode material for batteries, capacitors and solar cells. Graphene oxide is fluorescent, which makes it especially appropriate for various medical applications. One of the advantages of the graphene oxide is its easy dispersability in water and other organic solvents, as well as in different matrices, due to the presence of the oxygen functionalities. This remains as a very important property when mixing the material with ceramic or polymer matrices when trying to improve their electrical and mechanical properties.
