摘要：

Electrochemical polymerization of azure B from sulfuric acid solution was carried out by using cyclic voltammetry. The electrolytic solution consisted of 5.0 mmol - dm(-3) azure B and 0.3 mol.dm(-3) H2SO4. The temperature for polymerization was controlled at 20 degrees C. A blue film, i.e., poly(azure B) was formed on a platinum foil and had a electrochemical reversibility, stability and a fast charge transfer ability in the 0.5 mol - dm(-3) Na2SO4 with pH <= 4.0 solution. The currents of both anodic and cathodic peaks are proportional to v(1/2) at the scan rate (v) region of 25 and 600 mV . s(-1) on the cyclic voltammograms. The conductivity of poly(azure B) is 2.8 x 10(-6) S . cm(-1) at 20 degrees C. The UV-visible spectrum and Raman spectrum of the polymer are different from those of the monomer. A possible polymerization mechanism of azure B was also proposed.
