▎ 摘　　要

In this study, graphene oxide nano-platforms were functionalized/reduced (rGO-His) by a green reductant based on histamine. Additionally, the rGO-His was modified by zinc metal cations in two ways (I and II) and characterized by FT-IR, XRD, XPS, HR-TEM and FE-SEM. Then, by dynamic mechanical thermal analysis (DMTA), tensile test and thermogravimetric analysis (TGA) the mechanical/thermal properties of the epoxy composite coatings filled with rGO-His and rGO-His-Zn (I and II) were evaluated. Results of tensile and DMTA analyses proved significant increment in tensile strength, elongation at break, cross-linking density and thermal stability of the coating in the presence of rGO-His.
