Abstract

Metal free phthalocyanine grafted polypyrrole and cobalt metallated phthalocyanine grafted polypyrrole nanofibers were prepared by electrospinning method. The electrospun PPy and phthalocyanine grafted polypyrrole fibers were coated on indium tin oxide electrode surface for a proper investigation of the electrochemical activity of the fibers. Different methods were used to characterize the obtained fibers. Fourier-transform infrared spectroscopy, Scanning electron microscope and polarized optical microscope were used for their morphological characterization, while electrical behaviors of the nanofibers were characterized by direct current and electrochemical impedance spectroscopy measurements.
