“…Some studies have shown that graphene can also be used as a protective layer to prevent oxidation . In general, to prevent refined metal corrosion, several methods have been proposed, including inert metal or alloy coating, electroactive conducting polymer coating, self‐assembly monolayer coating, and the formation of oxidized layers on the substrate surface . However, these methods rely mainly on the physical properties of metals, such as optics, thickness, and electrical and thermal conductivity.…”

Currently, there is great interest in graphene-based devices and applications because graphene has unique electronic and material properties, which can lead to enhanced material performance. Graphene may be used in a wide variety of potential applications from next-generation transistors to lightweight and high-strength polymeric composite materials. Graphene, which has atomic thickness and two-dimensional sizes in the tens of micrometer range or larger, has also been considered a promising nanomaterial in gas-or liquid-barrier applications because perfect graphene sheets do not allow diffusion of small gases or liquids through its plane. Recent molecular simulations and experiments have demonstrated that graphene and its derivatives can be used for barrier applications. In general, graphene and its derivatives can be applied via two major routes for barrier polymer applications. One is the transfer or coating of few-layered, ultrathin graphene and its derivatives, such as graphene oxide (GO) and reduced graphene oxide (rGO), on polymeric substrates. The other is the incorporation of fully exfoliated GO or rGO nanosheets into the polymeric matrix. In this article, we review the state-of-the-art research on the use of graphene, GO, and rGO for barrier applications, including few-layered graphene or its derivatives in coated polymeric films and polymer nanocomposites consisting of chemically exfoliated GO and rGO nanosheets, and their gas-barrier properties. As compared to other nanomaterials being used for barrier applications, the advantages and current limitations are discussed to highlight challenging issues for future research and the potential applications of graphene/ polymer, GO/polymer, and rGO/polymer composites.

“…At macroscale, a surface can be covered by different materials including paints, 1 polymers, 2 organic layers, [3][4][5] metals, and alloys. 6 Conventional coating materials modify the structural and physical properties of the underlying structure which can result in undesired alterations. These effects are more drastic in reduced dimensions, especially in nanoscale systems.…”

First-principle calculations are employed to investigate the interaction of oxygen with ideal and defective MoS2 monolayers. Our calculations show that while oxygen atoms are strongly bound on top of sulfur atoms, the oxygen molecule only weakly interacts with the surface. The penetration of oxygen atoms and molecules through a defect-free MoS2 monolayer is prevented by a very high diffusion barrier indicating that MoS2 can serve as a protective layer for oxidation. The analysis is extended to WS 2 and similar coating characteristics are obtained. Our calculations indicate that ideal and continuous MoS2 and WS2 monolayers can improve the oxidation and corrosion-resistance of the covered surface and can be considered as an efficient nanocoating material. © 2014 Author(s)

“…The protective coating for metal and alloys can prevent metallic materials from chemicals corrosion and electrochemical environment degradation. [1,2] This is of essential significance for the applications of metallic materials, and further affects the society in terms of economy, industry, and safety. [3] However, most of the protective coatings suffer either from the short-term functionality or from the very thick coating layers which would alter the intrinsic properties of the protected metal substrates.…”

Oxidative Originators of Graphene Barrier Coating Grown on Surfaces

Graphene coating has been proposed to be a promising oxidation barrier for metals because of its chemical inertia and physical impermeability. Nevertheless, chemical vapor deposition (CVD)‐grown graphene on metal surfaces results in many structural defects and growth imperfections, which would serve as oxidative originators and favor a substantial galvanic corrosion at such interfaces in the long term. On this basis, oxidative originators including graphene structural defects and CVD growth imperfections of graphene on copper have been reviewed from the perspective of CVD growth of graphene. The associated oxidation processes and long‐term corrosion mechanisms as a protective coating for Cu are discussed. Finally, the remaining challenges and potential improvement of graphene and graphene‐like materials grown on surfaces as a barrier coating are outlooked. We aim to providing comprehensive knowledge about the relationship between various graphene defects/growth imperfections and the oxidation/corrosion mechanisms as a protective coating, seeking a roadmap to promote the development of cheap, powerful and effective barrier technologies based on such ultrathin two‐dimensional materials.
