Graphene oxide (GO) thin film possesses a 2D sheet structure and was synthesized indigenously via the enhanced solvothermal Hummer method. Conventionally, the redox approach can be a characteristic technique to fabricate GO films on an expanded scale. AFM characterization shows GO film had a 2D lamellar layer structure and a thickness between 3 to 5 nm. Heat treatment reduces the GO film to reduced graphene oxide (rGO). The crystallinity of GO thin film was recognized by XRD study. The typical characteristic 2θ peak appeared at 9.85 corresponding to (001) of the GO sheet for carbon with a d-spacing of 0.9 nm. Atomic force microscopy (AFM), scanning electron microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR) were employed to characterize the morphological and optical properties of the GO and rGO thin films. The electrical properties of the thin films were studied with current-voltage (I-V) properties. It is seen that the rGO thin film shows higher conductivity than GO and the value 5.1 x 10 – 4 S/cm, and also changes the morphology and optical properties. The morphological and optical properties change indicates that GO loses oxygen groups to form rGO. The reason behind the change of conductivity is the reduction of GO at 280 C temperature and decreased oxygen functional groups as compared to GO confirmed by FTIR. |
