Abstract
In this study, new clay/phosphate/epoxy nanocomposites (CPE nanocomposite) were fabricated to enhance the corrosion resistance of epoxy resin. The fabricated CPE nanocomposites were evaluated by electrochemical impedance spectroscopy (EIS), water permeability and UV-visible spectroscopy analysis. The evaluation was carried out on the coated carbon steel substrates in 0.5âM HCl solution. The experiments indicated that the best epoxy coating performance was obtained at 1.5% and 2.0% of CPE nanocomposites at ratio 50%:50% (clay: phosphate). The coated carbon steel by CPE nanocomposites showed higher coating resistance (Rc = 58.3 à 108 Ω cm2), than by the neat epoxy (Rc = 06.5âÃâ108 Ω cm2). The volume fraction of H2O absorbed by 1.5% of CPE nanocomposite is very low comparing with the neat epoxy coating. CPE nanocomposites are able to absorb the UV-Vis light with high efficiency.
