“…Therefore, various strategies have been developed to control the corrosion phenomenon. Techniques such as the use of electrochemical cathodic protection, surface treatment, green corrosion inhibitors and protective coatings have been applied to delay the corrosion process of metals [7][8][9][10]. In particular, organic coatings including epoxy coatings have been widely used in order to prevent the corrosion of metallic structures in modern industry.…”

“…The use of flush-mounted anode units (type AU-2M and AU-3M anodes ( [49] or [39])) reduces the influence of cathodic corrosion protection on ship motion resistance, while anode protection arrangement is fixed to the ship's hull and thus initiates an additional resistance. Resistance is also affected by microbial products that contribute to the fouling of the underwater part of the hulls of ships and floating facilities.…”

“…Furthermore, despite having numerous corrosion prevention strategies which are in operation, there is still a huge necessity to further increase the life of the components 8 . For instance, methods namely surface treatment, protective coatings, electrochemical cathodic protection and green corrosion inhibitors have been employed to slow down or completely inhibit the main electrochemical occurrence that led to the degradation of metals 9 , 10 . Interestingly, in modern industry, organic coatings have been widely adapted to prevent the corrosion of metallic structures.…”

In this study, acrylic-epoxy-based nanocomposite coatings loaded with different concentrations (0.5–3 wt.%) of graphene oxide (GO) nanoparticles were successfully prepared via the solution intercalation approach. The thermogravimetric analysis (TGA) revealed that the inclusion of GO nanoparticles into the polymer matrix increased the thermal stability of the coatings. The degree of transparency evaluated by the ultraviolet–visible (UV–Vis) spectroscopy showed that the lowest loading rate of GO (0.5 wt.%) had completely blocked the incoming irradiation, thus resulting in zero percent transmittance. Furthermore, the water contact angle (WCA) measurements revealed that the incorporation of GO nanoparticles and PDMS into the polymer matrix had remarkably enhanced the surface hydrophobicity, exhibiting the highest WCA of 87.55º. In addition, the cross-hatch test (CHT) showed that all the hybrid coatings exhibited excellent surface adhesion behaviour, receiving 4B and 5B ratings respectively. Moreover, the field emission scanning electron microscopy (FESEM) micrographs confirmed that the presence of the functional groups on the GO surface facilitated the chemical functionalization process, which led to excellent dispersibility. The GO composition up to 2 wt.% showed excellent dispersion and uniform distribution of the GO nanoparticles within the polymer matrix. Therefore, the unique features of graphene and its derivatives have emerged as a new class of nanofillers/inhibitors for corrosion protection applications.
