Conducting polymers have been synthesized electrochem. from 4-amino-3-hydroxynaphthalene-1-sulfonic acid (4A3HN1SA), 4-aminonaphthalene-1-sulfonic acid (4AN1SA) and 7-amino-4-hydroxynaphthalene-2-sulfonic acid (7A4HN2SA) on glassy carbon electrodes. The influence of the pos. potential limit on the potential cycling polymerization of 4A3HN1SA was studied, and a sufficiently high potential limit allowed better film growth. Under similar polymerization conditions, the three monomers showed different radical formation potentials and different voltammetric peak profiles. The effects of scan rate and solution pH on the electrochem. properties of the polymers were investigated, in the range between 10 and 200 mV s-1, all the modified electrodes showing a surface-confined electrode process. In the pH range from 2.0 to 9.0, the anodic peak potentials decreased linearly with increasing pH for all the three modified electrodes. The modified electrodes were characterized by electrochem. impedance spectroscopy in pH 4.0 and 7.0 buffer solutions The results showed a more porous poly(7A4HN2SA) film, which is less affected by pH change than the other two films. SEM of the polymer films also showed significant differences in their morphologies.
