| Description |
Corrosion protection performance of epoxy
polyamide coatings containing polypyrrole (PPy)
composites for steel has been studied. PPy and its composites have been synthesized chemically using potassium
permanganate and potassium per sulfate as
oxidants. The PPy has been characterized by four probe
method for conductivity, atomic absorption spectroscopy
for elemental analysis, and Fourier transform infrared
spectra for proving the incorporation of dopant in this
polymers. The X-ray diffraction (XRD) study has
revealed the presence of manganese dioxide in the polymer.
The elemental analysis and the thermo gravimetric
analysis measurements showed that the presence of
manganese dioxide in the polymer is about 75%. The
thermal stability of deprotonated polymer has improved.
Electrochemical impedance spectroscopic analysis indicated
that the epoxy polyamide/PPy-MnO2 coating
showed the maximum resistance value of 2.196 � 107 X
cm2 after 30 days immersion in 3% sodium chloride solution.
