| 1 | 2017 thesis | Synthesis of graphene oxide using electrochemical exfoliation method for electrode materials application Nurhafizah Md Disa This study aimed to synthesise and fabricate graphene oxide (GO) and reduced GO (rGO) assisted custom-made and commercially available surfactants to be used as nanofillers in various types of natural rubber latex (NRL). The method used in this study were one- and two-step methods of electrochemical exfoliation. The samples were characterized using electron microscopy, energy dispersive X-ray, micro-Raman, ultraviolet visible, Fourier transform infrared spectroscopies, X-ray diffraction, atomic force microscopy, thermogravimetric and four-point probe measurement. The GO/NRL nanocomposite samples were further characterized using the cyclic voltammetry and charge-discharge measurement. Meanwhile, measurement of the dye-sensitized solar cells (DSSCs) was performed on the optimized GO and rGO samples using Keithley 2611 source meter measurement. The findings show the optimum synthesis parameters for the production of GO were at electrolyte concentration of 0.01 and 0.1 M in synthesis time o..... 539 hits |
