| Description |
Polyaniline-phosphate polymer was prepared
chemically by oxidation polymerization of aniline in
phosphoric acid medium using ammonium persulphate.
The PANI-phosphate polymer was characterized by FTIR,
XRD, and SEM. The paints using PANI-phosphate as pigment
in acrylic and epoxy binder were prepared. The protective
performance of the coating formed on aluminum
alloy AA 2024 T3 was studied by electrochemical impedance
spectroscopy in 0.5% NaCl solution. Both the coating
systems have exhibited the coating resistance values above
1M O cm2 even after 50-days exposure in 0.5% NaCl solution.
Besides the anticorrosion performance of PANI-containing
coating is comparable with that of chromate-containing
coating.
