This article presents a method for synthesizing nanocomposite materials that protect against metal corrosion using a cerium modified 2-methylimidazole and graphene oxide modified octyl amine (GO-OA), denoted as Ce-Imi/GO-OA. The structural morphology of the material is evaluated using field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), and thermogravimetric analysis (TGA). The corrosion protection capability of the material is evaluated using the Tafel curve method, electrochemical impedance spectroscopy (EIS), and accelerated salt spray testing according to ASTM B-117 standards. The research results show that Ce-Imi/GO-OA has a metal protection efficiency of 96.4%. The epoxy coating containing Ce-Imi/GO-OA has the ability to protect the metal for up to 90 days when immersed in a 3.5% NaCl solution. Research results show that Ce-Imi/GO-OA has good dispersion ability in epoxy resin, forming a protective film that prevents the infiltration of corrosive environments.
