Study on Morphological, Optical and Electrical Properties of Graphene Oxide (GO) and Reduced Graphene Oxide (rGO)

In this work, graphene oxide (GO) is synthesized via chemical method (improved method) and reduced graphene oxide (rGO) using thermal treatment. The GO and rGO thin films were coated on a glass substrate by using drop casting method. The GO and rGO thin film were characterized by scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) to make sure the morphological and optical characteristics of the thin film. In addition, the electrical studies were performed by current-voltage (I-V) characteristic. The rGO thin film displays higher conductivity in comparison with GO which is 4.12 x 10-5 S/cm, and also affected the morphological (SEM) and optical properties (FTIR). Morphological and optical data confirms that rGO losses the oxygen groups compare to GO.
