چکیده

The present study involved the synthesis of graphene oxide and polyanthranilic acid, along with the oxidation of multi-walled carbon nanotubes, to produce MWCNTs-COOH. The polyanthranilic acid solution was mixed with epoxy resin to prepare the mother solution. Then the polymeric nanocomposites (GO/Epoxy-PANA, MWCNTs/Epoxy-PANA) were prepared. The prepared materials were characterized by XRD, EDX and SEM. Finally, polymeric coatings were prepared, which consist of adding the mother solution and hardener with graphene oxide and oxidized carbon nanotubes, which are corrosion resistant. It was also found that the inhibition efficiency increased in the case of MWCNTs / Epoxy-PANA more than GO / Epoxy-PANA. On the other hand, the coating samples were examined by (SEM) and the results were recorded. The effects on activation energy (Ea), enthalpy (∆H) and entropy (∆S) were also studied.
