Graphene represents an innovative material, which possesses a unique combination of properties. The remarkable features of this material allow it to be often used as a reinforcing filler in organic based coatings. The excellent conductivity and mechanical strength properties of graphene produce a significant increase in the performance of the polymer matrix. Recently, however, scholars have focused on the barrier effect properties that can be provided by graphene flakes to obtain high corrosion resistance coatings. If well distributed in the polymeric matrix, in fact, the graphene-based sheets are able to provide a high resistance to the passage of aggressive ions, fundamental for the development of corrosion processes on the metal substrate. The distribution of graphene-based fillers, however, is a critical aspect, which can be improved by means of certain oxidation and functionalization processes of graphene flakes. Recent studies have shown the possibility of combining the excellent features of cataphoretic processes with the remarkable protective properties of graphene-based fillers in the creation of high-performance multifunctional composite coatings. The functionalized graphene oxide flakes, in the correct amount, can in fact increase the protective performance of cataphoretic coatings, as well as providing additional features such as mechanical strength and high conductivity.
