Abstract
Electrochemical polymerization of 2-chloroaniline on platinum electrode in acid medium was carried out under various reaction conditions, altering temperature, current density, hydrochloric acid, and monomer concentrations and time duration. The initial rate of the electropolymerization reaction is small and the orders are found to be 1.00, 1.06, and 0.96 with respect to current density, acid, and monomer concentrations, respectively. The apparent activation energy (Ea) is found to be 44.336 kJ mol 1. The rate law is RP ¼ K2½D 1:00½HCl 1:06½M 0:96. The
obtained polymer films are characterized by 1H-NMR, elemental analysis, IR,
and cyclic voltammetry. The mechanism of the electropolymerization reaction is
also discussed. The thermogravimetric analysis (TGA) is 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.
