Abstract :

In this study a direct electrochemical copolymerization of pyrrole-formyl pyrrole (Py-co-FPy) was carried out by copolymerization of formyl pyrrole and pyrrole in LiClO4 aqueous solution under constant current of 480 µA for 200 s. The (Py-co-FPy) copolymer was characterized using field emission scanning electron microscope (FESEM), energy-filtering transmission electron microscope (EFTEM), thermal gravimetric analysis (TGA) and Electrochemical Impedance Spectroscopy (EIS). The FESEM images showed that the synthesized copolymer had a hollow whelk-like helixes structure. Moreover, the whorls on the bodies of (Py-co-FPy) copolymer whelk have well-ordered periodic nanostructures that provides a great high ratio of surface to volume. The Impedance study results confirm that (Py-co-FPy) copolymer layer can improve the electron conduction 2.5 times higher than PPy. The conjugated structure between Py and FPy in the presence of methine group can cause the enhancement of conductivity compared to polypyrrole. TGA analysis reveals that the Py-co-PPy copolymer has more thermal stability compared to polypyrrole.
