EXTRACTION OF WRINKLED GRAPHENE FROM HYDROCARBON A.V.Ramya1, Anu N. Mohan2, B.Manoj1 1 Dept. of Physics, Christ University, Bangalore; 2Dept. of Physics, Jain University, Bangalore Graphene oxide has grabbed intensive research interest due to its part as a promising precursor for large-scale and cost-effective production of graphene-based materials. Generally, graphene oxide is derived from graphite by controlled oxidation. In contrast, a liquid hydrocarbon was chosen as precursor to synthesize graphene oxide. Distillate fraction of crude oil was subjected to thermal decomposition and the hydrocarbon soot thus obtained was treated by a modified Hummer’s method to produce graphene oxide. X-ray Diffraction (XRD) pattern of hydrocarbon soot exhibited turbostratic graphitic structure with interlayer spacing (d002) ~ 3.54 Å. The same of graphene oxide revealed the formation of a heterogeneous structure with a physical mixture of graphene oxide, graphite and amorphous like carbon, with lateral size (La) and stacking height (Lc) ~ 3 nm. In the Raman spectrum of soot, the positions of D and G bands were similar to that of graphite with ID/IG ~ 0.82 while those of graphene oxide revealed an increase in intensity and blue shift due to oxidation, with ID/IG ~ 0.91. Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Photoelectron Spectroscopy (XPS) of the virgin sample revealed the functional groups present while that of graphene oxide affirmed the incorporation of additional epoxy, hydroxyl, carboxyl and carbonyl groups into the carbon backbone as a result of oxidation. Atomic Force Microscopy (AFM) assured the formation of few layer graphene and Scanning Electron Microscopy (SEM) confirmed the formation of nanoscale wrinkled graphene oxide thereby supporting XRD and Raman analysis results. Solubility and stability of the synthesized graphene oxide in a variety of solvents for varying time periods was also investigated.
