Synthesis and Corrosion Protection Performance of Polydiphenylamine
No full textIn recent years, the conducting polymers
are used in organic coatings as a replacement of chromate
based pigments. The effectiveness of polydiphenylamine
(PDPA) in the vinyl coating towards the corrosion protection
of steel in acidic environment has been found out.
The polymer PDPA was synthesized by chemical oxidation
of diphenylamine by ammoniumpersulfate in hydrochloric
acid medium. The polymer was characterized by FTIR and
XRD. The corrosion protection performance of the PDPA
containing 0–5% in vinyl coating on steel in 0.1N HCl has
been assessed by electrochemical impedance spectroscopy.
Coatings containing more than 3% PDPA are found to
offer excellent corrosion protection of steel in acid media
due to redox property of PDPA
