 This paper discusses the use of graphene oxide, geo-nanoparticles as a potential corrosion inhibitor for acrylic-epoxy-based nanocomposites. It was found that the incorporation of geo-nanoparticles and polydomethylzolin, PDMS, into the polymer matrix resulted in improved surface hydrophobicity, increased thermal stability, and better dispersion of the geo-nanoparticles. This study suggests that geo-nanoparticles can be used as a promising corrosion inhibitor for acrylic-epoxy-based nanocomposites.
