摘要

Characterization of polyaniline (PANI) byelectrochemical and spectroscopic techniques are presented. Theelectrochemical investigation reveals the influence of the dopantacid on the kinetic parameters of polyaniline films:exchangecurrent density (I0) and the cathodic transfer coefficient(αC).UV-Vis spectra of thin films of polyaniline in N-metilpyrrolidine solutions indicate the increase of the absorbancewith the number of deposition cycles, N. The inhibition ofpolymer degradation in thick films was confirmed by these spectra.
