Graphene oxide: the mechanisms of oxidation and exfoliation

Hummers' method is a chemical process that can be used to generate graphite oxide through the addition of potassium permanganate to a solution of graphite, sodium nitrate, and sulfuric acid. It is commonly used by engineering and lab technicians as a reliable method of producing quantities of graphite oxide. It is also able to be revised in the creation of a one-molecule-thick version of the substance known as graphene oxide.
