“…Due to the addition of nano-CeO 2 , the graphene oxide was more uniformly dispersed in the epoxy resin coating, and the resistance of the coating to water penetration was enhanced. [52] In addition to the above common nano-metal oxides, Fe 3 O 4 nanoparticles are often used as fillers for coating anticorrosion because of their low toxicity, easy preparation, and low cost. Chhetri et al reported the synthesis of Fe 3 O 4 -modified N-doped GO nano-hybrid (Fe 3 O 4 -NRG).…”

Graphene oxide is an excellent additive in anti-corrosion coatings because of its chemical inertness, permeation resistance, and high mechanical strength. In addition, the presence of oxygen-containing functional groups on the surface of graphene oxide gives it hydrophilic properties while efficiently promoting chemical functionalization, thus enhancing its dispersibility and corrosion inhibition properties. Modified graphene oxide corrosion inhibitors are a new field of interest for corrosion scientists. This paper presents the primary research on graphene oxide as a novel corrosion protection material, including the synthesis of modified graphene oxide and its remarkable performance in corrosion protection coatings and corrosion inhibitors. Different kinds of modified graphene oxide coatings are outlined, including the research progress on modified graphene oxide innovative coatings with pH response in recent years. The synthesis of modified graphene oxide corrosion inhibitors and their corrosion inhibition mechanisms are reviewed. Finally, the typical role of modified graphene oxide in coatings and the prospect of its research are discussed.

In the marine service environment, metal materials have a serious risk of corrosion. The corrosion rate of metal materials will be accelerated by the dual action of temperature change and alkali salt in saline-alkali environment. In order to delay the metal materials’ corrosion rate and prolong their service life, this paper used a CeO2–GO (4:1) nanocomposite prepared by the hydrothermal synthesis method to make an anticorrosion coating. The anticorrosion performance was evaluated by stereo microscope and 3D images of the corrosion site were fitted for calculation. The state evolution of the CeO2–GO (4:1)/EP coating immerged in a simulated saline-alkali solution was studied by open circuit potential (OCP), electrochemical alternating current impedance spectroscopy (EIS), Mott–Schottky curve and Tafel curve. The results indicated that CeO2–GO (4:1) nanocomposites exhibited good resistance compared with graphene oxide and nano cerium oxide in a simulated saline-alkali environment. The research in this paper lays a firm theoretical foundation for the application of nano cerium-oxide-modified graphene oxide anticorrosive coating in saline-alkali environment engineering.
