Abstract

• This research studied the synthesis of graphene oxide via a low-cost manufacturing method. The process started with the chemical oxidation of commercial graphite powder into graphene oxide (GO) by Hammer’s method. It is proven that this method is promising way to synthesize graphene oxide on a large scale. GO nanocomposites thin films have been successfully deposited on ITO glass substrate. The films were deposited by spin coating method and heat treated at 80°C for 24 h. The synthesized graphene oxide was analyzed by X-ray diffraction (XRD), Energy dispersive Xray (EDX), Fourier Transform Infrared spectroscopy (FTIR), UV-Vis spectroscopy and Field Emission Scanning Electron Microscopy (FESEM). The XRD pattern reveled a (0 0 1) diffraction peak, signifying the successful synthesis of GO. The elemental composition of GO was characterized by EDX analysis. The content of C is 67.35 % and the content of O is 29.75%. The mass ratio of C/O is 2.26. The results of FT-IR showed that C-O bond, O-H group with water molecules and C=C bond with graphene oxide. UV-Vis spectra of GO exhibited maximum absorption peak at 290 nm. SEM image confirmed that the size and synthesis of GO particles.
