Comparison of homo and copolymer of pyrrole and aniline electrosynthesized on ferric ion reduction
View through CrossRef
In this study, homo and copolymer of Aniline (Ani) and Pyrrole (Py) was electrosynthesized on composite graphite in acetic acid medium containing KCl as supporting electrolyte. The ability of electrosynthesized homo and copolymer on ferric ion reduction was compared and evaluated. The results show that the reduction properties of polyaniline (PAni) is greater than copolymer of aniline and pyrrole (Poly(Ani-co-Py)) and copolymer is more than polypyrrol (PPy). The FTIR and UV-visible spectra indicated that the increase of aniline monomer in the copolymer chain enhances the ferric ion reduction ability. Electrochemical Impedance Spectroscopy (EIS) was also used for further investigation. It was shown that the increase of aniline ring in the copolymer chain reduces the charge-transfer resistance and thus increases the reduction effect. The structure and morphology of homo and copolymer was confirmed by SEM, EDX and FTIR.
