Abstract
Electropolymerization of 3-chloroaniline on a platinum electrode in an acid medium was carried out under different reaction conditions of temperature, current density and hydrochloric acid and monomer concentrations with du- ration time. The initial rate of the electropolymerization reac- tion was small, and the orders were 0.99, 0.96 and 1.2 with respect to current density and acid and monomer concentra- tions, respectively. The apparent activation energy was 41.6 kJ/mol. The rate law was Rp k2(Current density) 0.99 (HCl) 0.96 (Monomer) 1.2 . The obtained polymer films were char- acterized by 1 H-NMR, elemental analysis, IR spectroscopy, and cyclic voltammetry. The mechanism of the electropolymeriza- tion reaction is also discussed. Thermogravimetric analysis was used to confirm the proposed structure and determination of the number of water molecules in the polymeric chain unit. X-ray and scanning electron microscopic analysis are used to investigate the surface morphology. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 94: 941-953, 2004
