Characterization and Conductivity Studies of Graphene Oxide with Different Degrees of Oxidizing Agent
Original language description
Different degrees of potassium permanganate (KMNO4) was used in the synthesis of graphene oxide (GO). In characterization analysis, the appearance of IR band attributes to O-H, C=C, C-OH and, C-O-C can be observed at around 3500 cm(-1), 1650 cm(-1), 1400 cm(-1) and, 1200 cm(-1) respectively. The UV-Vis spectroscopy revealed, GO with more KMnO4 shows increment in absorption and wavenumber due to more concentration of GO and stacked layers of GO. Nevertheless, a high level of KMnO4 results in a low density of GO. Analysis from Semiconductor Parameter Analyzer (SPA) revealed, a low oxygenated functional group from low-level KMnO4 produces less band gap open and thus, yielding high conductivity.
