Polypyrrole Modified Graphite Electrode for Supercapacitor Application: The Effect of Cycling Electrolytes

Abstract: Graphite electrode was modified by polypyrrole (PPy) thin film. PPy was electrodeposited potentiostatically by applying-1.5 V from acidic aqueous solution having pyrrole monomers. The waiting time of deposition solution effect the surface coverage of resulted films. PPy modified electrodes fabricated by old solution have lower surface coverage than PPy obtained from freshly prepared solution. PPy films were transferred to aqueous (acidic, neutral, alkaline) and a non-aqueous (Deep Eutectic Solvent) solutions f… Show more

“…Figure b shows the deposition CV for Ppy deposited on a Pt WE (3 mm dia.) in 1ChCl:2Phenol DES containing 0.7 M of pyrrole at a scan rate of 50 mV s –1 for 10 cycles and a potential range of −0.4 to 1.4 V. The CV shows both oxidation and reduction waves, characteristic of Ppy electrodeposition and growth, like that observed by Yavuz et al It is clear from Figure b that the growth of Ppy film increases with the increase of the scan number, demonstrated by an increase in the redox peaks. Inspection of the deposited electrode after polymerization shows the formation of a black solid polymer on the surface of WE, as shown in Figure e.…”
