  • Abstract:
  • The Polyaniline coatings (PANI) have been synthesized on low carbon steel (LCS) substrates by galvanostatic method. An aqueous solution of oxalic acid used as supporting electrolyte. These galvanostatic coatings were synthesized by keeping constant current density at 0.66 mA/cm2. The potential - time behavior recorded during synthesis reveals that in PANI coating formation the passivation is essential step through the formation of iron oxalate interphase. This interphase acts as a barrier against the further dissolution and facilitate the deposition of PANI. The coatings are uniform, and strongly dark green colored which enhances the electrochemical performance and stability of the LCS substrate for various applications. The PANI coatings characterized by FTIR and SEM, its results shows successful synthesis of PANI also indicates that the oxalic acid is a suitable medium for the ECP of PANI on the LCS substrate.
