The graphene-based product involved in all the GnP-Cu composite electrodeposition solutions reported in this work is named G7Nan. G7Nan is a commercial product produced by a proprietary graphite exfoliation method by Nanesa S.r.l., it has an average lateral size of 7-15 µm and a thickness of 20 nm (41 atomic layers). The metal substrate selected as the base for all coatings prepared in this work were DC01 steel plates with a total area per piece of 0.228 dm . All the reactants used, except for G7Nan, were technical purity grade and used as supplied.
