ABSTRACT
The arrival of novel organic and inorganic nanomaterials in recent years, particularly nanostructured carbons, conducting polymers, and metal oxides, has enabled the fabrication of various energy devices with enhanced performance. A conventional method is utilized for the preparation of reduced graphene oxide/polyaniline (rGO/PANI) composite, where ammonium persulfate (APS) is added to the acidic solution of graphene oxide (GO) and aniline monomer and further reduced using hydrazine. Here in-situ polymerization is conducted to polymerize the aniline monomer. An investigation is carried out by varying the amount of GO while keeping amount of aniline constant to obtain the best composition. The characterizations reveal the structural property, purity of the composite, the vibrational and rotational characteristics and further shows proper loading of PANI on rGO. As investigated earlier rGO/PANI composite then to have an energy density of about 13.9 Wh kg-1 and specific capacitance around 600 Fg-1. Therefore, electrodes made out of rGO/PANI composite can be considered as a promising milestone for the fabrication of low cost, better performance supercapacitor.
