Corrosion Inhibition Studies of Poly (MPDMA C16 -co-NCA) on Mild Steel in 0.05M H2SO4
Keywords:
Copolymer, Impedance, Inhibition Efficiency.Abstract
Copolymers of MPDMAC16 and MPDMAC18 with N-substituted acrylamide were synthesized in DMF solution using AIBN as initiator. Since MPDMA C16 and MPDMA C18 monomer was in the form of an aqueous solution (50 %) and the N-substituted acrylamide are in DMF solution was used for copolymerization. The synthesized copolymer MPDMA C16 and MPDMA C18 with NCA are characterized by 1H-NMR, 13C-NMR, FTIR, and TGA analysis. The corrosion effect of copolymer on the mild steel in 0.05M H2SO4 solution was studied by potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) method. The % IE increases with increase in concentration fits the experimental data for the studied compound
