Abstract: Nanotechnology is a cutting-edge research in materials, energy, sensors, biotechnology and defence systems. One of the crucial bottlenecks of modern technology is cost and scalability. In this respect, Graphene Oxide (GO) has gained significant attention. GO is often described as an electrical insulator, due to the disruption of its sp2 bonding network. In order to recover the honeycomb hexagonal lattice and the electrical conductivity, the reduction of the GO has to be achieved. This remains an important property when mixing with polymers or ceramics matrixes to improve their electrical and mechanical properties. The GO used in this study was prepared by and modified Hummer’s method. The structural properties were investigated by X-ray diffraction. The optical properties were studied by UV-Vis absorption spectra and FT-IR spectroscopy; furthermore, scanning and transmission microscopy analysis was done to study its morphology. In the study we successfully synthesized GO by modified Hummer’s method, and the results indicated higher interlayer spacing.
