The current effort discuss the fabrication of improve electrode materials for supercapacitor comprise of surfactant doped polypyrrole-carbon materials composites integrated with graphene, amine functionalized multiwalled carbon nanotubes and hybrid carbon assembly. The spectroscopic characterizations demonstrate the establishment of a well-built state of charge swap complex among surfactant doped polypyrrole and carbon materials that disclose the occurrence of polymer-carbon phases and promote well-built polarization. The electrodes are assembled in the three electrode cell configuration with graphite sheet current collector. The composite SDBSDPPy-HC holds a specific capacitance of 1086 F g(-1) at scan rate 5 mV s(-1) in 6 M KOH electrolyte solution. SDBSDPPy-HC exhibit only 10% losses in specific capacitance over 2500 cycles i.e. 90% preservation of specific capacitance at a current density 1 A g(-1).
