Electrochemical Polymerization of Pyrrol/Thiophene Conducting Copolymer Nanofibrilla Arrays and Characterization

Abstract

Abstract: Copolymer nanofibrilla arrays composed of pyrrole and thiophene were prepared by synthesizing the desired polymer within the pores of the porous anodic aluminum oxide (AAO) template membrane. The results of SEMand TEMreveal that the obtained copolymer nanofibrillas have uniform and well-aligned arrays. The results of infrared spectra and cyclic voltammetry indicate that the obtained nanofibrilla arrays are copolymer rather than mixture of polypyrrole and polythiophene. The higher potential favored the incorporation of thiophene units into the copolymer nanofibrillas.
