The electropolymerization of 6-amino-m-cresol (AmC) on a platinum electrode was studied in 0.1 M Na2SO4 solution containing 5 x 10(-3) M 6-amino-m-cresol at different pHs using cyclic voltammetry technique. Voltammetric results showed that oxidation of 6-amino-m-cresol produced a passivating polymeric film on the platinum surface at all pHs studied. Synthesized polymer has bronze color on platinum. To investigate the structure of poly-6-amino-m-cresol (poly-AmC) films FTIR technique was employed. The spectroscopic results indicate that polymer chain consist of ring opened units rather than phenoxazine structure. (c) 2005 Elsevier B.V. All rights reserved.
