SYNTHESIS AND CHARACTERIZATION OF POLYANILINE FILMS DOPED WITH H2SO4
Abstract
In the report, the polyaniline (PANI) films were grown on Pt/SiO2 microelectrodes surface directly by a simple cyclic voltammetry method. This method has been helped the pure PANi films synthetic with the dopand of H+ ions in aqueous sulfuric acid (H2SO4) solutions into PANi matrix. The changing about the mol ratio of aniline monomer and dopant and reaction time have been optimized to better surface morphology of the PANI samples. The transformation from nano-seeds bunch to uniform nano-wires with their diameter of a few dozen nm and length about µm were indicated by Scanning electron microscopy (SEM). The molecular structure of PANI was studied by FTIR spectroscopy.
