This study can be categorized into two parts. The first part aims to obtain nano-sized, new promising active electrode materials for supercapacitor application by using commercially available monomer. The polymer of N-methylpyrrole was studied to obtain nano-size form by applying a template synthesis method. Its morphology characterization was performed by scanning electron microscopy (SEM). To enhance the electrical conductivity of the obtained polymer, template synthesized poly(N-methylpyrrole) with gold nano particle was combined. The resulted polymer/gold material has been characterized by SEM techniques. The second aim was to build a polypyrrole based solid state supercapacitor prototype by using proton polymeric electrolytes having the common acids of H3PO4. The effect of the duration of polymerization on electrode materials for supercapacitor devices was also studied. The performance characteristics of fabricated supercapacitors were evaluated by ac. electrochemical impedance spectroscopy, cyclic voltammetry techniques and the study of surface morphology of the active electrodes were performed by scanning electron microscopy.
