“…According to the Nyquist plots and impedance values (ź), the corrosion resistance of the uncoated LCS discs was lower than that of the coated discs because the polymer films inhibit the penetration of ions and water into the coating and the subsequent electrochemical reactions at the coating/metal interface, leading to the improvement of the barrier performance of the polymer coating [46,47]. This demonstrates the coating's effectiveness in protecting the LCS discs surface against corrosion.…”

In the current study, a novel conductive polymer poly 6-((4 acetylphenyl) carbamoyl) cyclohex-3-ene-1-carboxylic acid (PACC) was created by polymerized 6-((4 acetylphenyl) carbamoyl) cyclohex-3-ene-1-carboxylic acid (ACC) monomer using the electropolymerization process. The resulting polymer was characterized using Fourier Transform Infrared Spectroscopy (FTIR). The ability of this polymer to protect the alloy from corrosion was studied at temperatures ranging between 298 and 328 K. The ability of these coatings to stop corrosion on the surface was assessed by measuring the corrosion potential (Ecorr) and the corrosion current (icorr) using a potentiostat. Adding nanoscale metal oxides (zirconium dioxide (ZrO2) and magnesium oxides (MgO)) enhanced the efficiency of this polymeric coating. The protection efficiency of the polymer alone was 77.5%; this efficiency increased to 85.0% and 99.7% in the presence of nano ZrO2 and MgO, respectively. Kinetic and thermodynamic parameters (Ea, H, and S) were calculated for uncoated and coated LCS. An atomic force microscope (AFM) studied the coating surface morphology. Electrochemical impedance spectroscopy (EIS) was used to evaluate the coating resistance.
