Abstract
Electropolymerization of 3-methoxyaniline on platinum electrode in acid medium
was carried out under different reaction conditions such as temperature, current
density, hydrochloric acid, and monomer concentrations with duration time.
The initial rate of the electropolymerization reaction is small and the orders are
found to be 0.99, 0.98, and 0.97 with respect to current density, acid, and monomer
concentrations, respectively. The apparent activation energy (Ea) is found to be
59.673KJ mol 1. The rate law is RP ¼ K2[D] 0.99 [HCl] 0.98 [M] 0.97. The obtained
polymer films were characterized by 1H-NMR, elemental analysis, IR, and cyclic
voltammetry. The mechanism of the electropolymerization reaction has also been
discussed. The thermogravimetric analysis (TGA) 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 were used
to investigate the surface morphology.
