Abstract:

This particular dissertation aims to preparing graphene oxide GO and reduced graphene oxide RGO. More specifically, the aim was to optimize the process of oxidizing graphite and preparing graphene oxide. For this reason various graphite oxide compositions were made by oxidation with potassium permanganate. High importance was given in the detailed control of the experimental oxidation conditions, as these significantly affect the properties, form and even the quantity of the final product.

Aqueous suspensions of graphene oxide were then prepared by exfoliating graphite oxide in aqueous solutions under the influence of ultrasound radiation. Subsequently, various reducing agents such as ascorbic acid, sodium boron hydride and hydrogen iodide were added to the graphene aqueous suspensions to prepare the reduced graphene oxide RGO.
