Abstract

Graphene is a new material, first isolated in 2004, consisting of one to a few atomic layers of carbon in a lattice sheet structure. Graphene has high tensile strength, high surface area, very low electrical resistance, and various other special properties that make it an excellent material for use in emerging technologies in the categories of electrical components, energy systems, and high strength applications. The production scale of graphene sheets and its variations is currently limited to laboratory use, with a great amount of current research going into the development of manufacturing techniques of the material. I conducted experiments to analyze the scalability of graphene oxide synthesis through the sonication method. The synthesis of graphene oxide was conducted at various scales, as possible with the available resources, and for varying lengths of time and the resulting products were analyzed for quantity and quality. Raman spectroscopy was used to characterize the sheet size and purity of produced graphene oxide. The collected data was used to evaluate the relationship between factors associated with the scaling of the synthesis process.
