The influence of the oxidation method on the size of reduced graphene oxide

Derivatives of graphene have become important materials due to their excellent properties. Graphene oxide and reduced graphene oxide are especially interesting because they are relatively easy, cheap and quick to produce. Among many possible applications, reduced graphene oxide is a good candidate for sensor applications. Its properties can be controlled at the production stage. The precursor used and the method of oxidation have a significant influence on its properties. Therefore, it is worth taking a closer look at them. In this paper we analyse the influence of the oxidation method on the size of the reduced graphene stock, which determines the sensitivity of the rGO layer. We used AFM microscopy for this purpose.
