Abstract

In this study the effects of polyNethylaniline PNEA monolayer coating and PPY/PNEA and PNEA/PPY bilayer coatings which were formed on the low carbon steel LCS surface by electropolymerization in 01 M monomer + 03 M oxalic acid medium on the corrosion of the LCS in 1 M H2SO4 medium have been investigated LCS electrodes which were coated with each of these conductive polymer layers were held in 1 M H2SO4 medium for various time periods in order to obtain current potential curves and with the help of these curves the corrosion parameters have been determined Experimental findings show that the LCS coated with polymer layers prevent the corrosion of bare LCS in 1 M H2SO4 medium and bilayer PPY/PNEA and PNEA/PPY coatings are better than monolayer PNEA coating In order to elucidate the interaction between the coatings and the metal theoretical calculations have been done using AM1 semiempirical method The calculated data have been found to support experimental findings
