Graphical abstractDisplay OmittedHighlights?Designing an approach to surface modifying graphene oxide nanosheets and clay lamellae.?Enhancing the dispersion of the nanoparticles in epoxy and obtaining an exfoliated morphology through mechanical mixing.?Toughening the epoxy-based nanocomposite coating by optimizing a mixing ratio of the modified clay and graphene oxide.AbstractClay nano-platelets (NC) and Graphene oxide nanosheets (GO) are functionalized by the aid of 1,4- butanediol diglycidyl ether (BDDE) through an aminosilane coupling agent, i.e. 3-Triethoxysilyl propylamine (APTES). The products obtained from the modification process are characterized by visual assessment, FTIR, XRD, TGA, UV–vis, AFM
