In this study the anticorrosion performance of a clear epoxy coating was enhanced by the incorporation of modified zinc into the polymer matrix. The structural macroscopy by X-ray diffraction (XRD). Corrosion performance of the coated copper specimens was investigated employing polarization measurements and electrochemical impedance spectroscopy (EIS) in 3% NaCl solution. Incorporation of 5 wt% zinc possessed the best corrosion performance. The electrochemical results are completely in agreement with the morphological results of the surface obtained from scanning electron microscopy (SEM). For the theoretical study, complete geometry optimization of 4, 4′- Ethylene bis (N, N diglycidylaniline) was performed using the Density Functional Theory (DFT). The Gaussian 03W software package was used in the calculations.
