Enerji Depolanması İçin Tartarik Asit Katkılanmış Polipirol Bazlı Süper Kapasitör Malzemelerinin Sentezi

Abstract

In this study, the polypyrrole films as a supercapacitor material were electrochemically synthesized on platinum and stainless steel electrodes in an acetonitrile solution containing pyrrole, tartaric acid and Triton X-100. The polymers were characterized by cyclic voltammetry, FTIR, Raman and EDX methods. Their morphologies were also investigated by scanning electron microscopy. The capacitive properties of resulting coatings were investigated in H2SO4 water solution by using cyclic voltammetry, electrochemical impedance spectroscopy and the galvanostatic charge-discharge tests. It was determined that tartaric acid and Triton X-100 improved the capacitive behavior of polypyrrole coating and their specific capacitance were 379 F g-1 for Pt foil and 367 F g-1 for 316Ti SS.
