The Electrochemical Response of Graphene Oxide

GO is by no means a new material, with first reports emerging around 1859. Structurally it constitutes single atomic layers of functionalised (oxygenated) graphene that can readily extend up to tens of pm in lateral dimension. GO can be viewed as an unconventional type of soft material as it carries the characteristics of polymers, colloids, membranes and is an amphiphile [102, 103]. The specific structure of GO is debatable and Fig. 1.4 (found in Chap. 1) shows the various
