Surface morphology of electrochemically synthesized H2SO4-doped polypyrrole (PPy)

Abstract

Sulfuric acid doped Polypyrrole (PPy) film had been successfully synthesized using electrochemical synthesis in aqueous solution. A 13.0 V fixed potential was used in the electrodeposition of PPy in aluminum plate electrodes with sulfuric acid as a medium (electrolyte). Scanning electron microscopy was used to characterize the morphology of the fabricated samples. Data from the characterization show that surface roughness increases with the concentration of electrolyte.
