Polypyrrole (PPy) was electrochemically deposited by cyclic voltammetry onto glassy carbon electrode from acidic micellar solution. The effect of acidic micellar solution on capacitive property were characterised using cyclic voltammetry. The specific capacitance of the PPy reached the value of 353.37 F g−1after cycling in 0.5 M H2SO4 at 10 mVs−1. Presence of sodium dodecyl sulphate (SDS) decrease the polymerization potential andaffect the microstructure of the obtained polymer and the pull of SDS anion, from the polymer backbone, during dedoping change the morphology of the obtained polymer, which enhanced the polymer specific capacitance. Also, the surface morphology of the resulting polymer films was characterised by scanning electron microscope.
