... formulation. To achieve this, graphene-modified zinc-rich epoxy coatings (G-ZRE) were developed, containing varying concentrations of 0.05 wt% and 0.2 wt% graphene in a matrix of 65 wt% zinc-rich epoxy. Electrochemical impedance spectroscopy (EIS) was employed to assess the effect of graphene on the corrosion...
