| Description |
For the first time, poly (o-anisidine-co-metanilic acid) (PASM) was deposited on mild steel substrate by
electrochemical polymerization of o-anisidine and metanilic acid monomers in aqueous solution of 0.1M
H2SO4. The electrochemical polymerization of o-anisidine takes place in the presence of metanilic acid
monomer and uniform, strongly adherent coating was obtained on the substrate. The electroactivity of
copolymerwas studied by cyclic voltammetry and AC impedance techniques. There is an increasing anodic
current due to oxidation of metanilic acid monomer at the surface of the electrode when the applied
potential is cycled from −0.2V to 0.8 V. These deposits were characterized by Fourier transform infrared
(FTIR) spectroscopy, UV–vis and TG/DTA techniques. The effect of various concentrations of PASM copolymer
solution in acid rain corrosive media has been studied through potentiodynamic polarization, AC
impedance and I–E curvemethods. The soluble form of polymeric solution provided better anti-corrosive
behavior in artificial acid rain solution.
