“…Additional peaks can be associated to C-OH bonds (285.4 eV), C-O-C (286.4 eV), C=O (287.4 eV) and C-OOH (288 eV) functionalities, respectively 44 – 46 . Nonetheless, the main peak occurring at 284.4 eV accounts for more than 80% of C states and reflects the presence of graphitic bonds, in good accordance with the literature on graphene CVD growth 47 , 48 . Interestingly, the chemical states representing higher oxidation states as C=O and C-OOH functionalities increase with the treatment temperature, as shown in Figure S8 , suggesting that extreme growth conditions can be detrimental to the purity of graphene.…”

The development of 2D nanomaterial coatings across metal surfaces is a challenge due to the mismatch between the metal microstructure and the nanoscale materials. The naturally occurring thin oxidative layer present across all metal surfaces, may lead to low adherence and connectivity. In this paper, graphene/titania/Titanium hybrid films were for the first time fabricated by a single step chemical vapour deposition process across Titanium foils. The presence of graphene as a dopant was found to enhance the photocatalytic performance of the final products, applied to the degradation of organic molecules and to lead to Schottky-like junction formation at the metal/oxide interface. These Schottky junctions, where vacancies are present across the titania material due to the graphene doping and where Ti3+ ions are predominantly located, yield enhanced catalytic performance. The highest degradation rate was found to be 9.66 × 10−6 min−1, achieved by the sample grown at 700 °C for 5 min, which was 62% higher than the sample just treated at that temperature without graphene growth. This work provides evidence that graphene may be grown across pure Titanium metal and opens new avenues in biomedical devices design, tribological or separation applications.

“…Anisur et al [209] prepared graphene films on the surface of nickel via a CVD method and investigated the role of hydrogen flow and the cooling rate during graphene growth on the barrier properties and defect density of the film. Electrochemical impedance spectroscopy (EIS) and potentiodynamic tests on the samples immersed in a 0.1 M NaCl solution showed that graphene coatings prepared on Ni in an environment without H 2 flow offer nearly one order of magnitude superior corrosion resistance than that of uncoated Ni.…”

Among the many potential applications of graphene and graphene-based materials, their use as protective films or as additives in coatings for corrosion protection has seen an increased level of interest in the last decade. Much of this interest is motivated by the need to implement additional functionalities, to enhance anti-corrosion performance and to ultimately extend the service life of metallic structures. Pristine graphene films, with their impermeable nature allied to flexibility and mechanical strength, appear as particularly attractive candidates for barrier films against corrosive agents, while graphene-based materials such as graphene oxide and reduced graphene oxide offer a wide range of opportunities for their dispersion in polymeric matrices for composite anti-corrosive coatings. Simultaneously, considerable progress in the development of scalable graphene and graphene-based materials production techniques has been made during the last several years. Currently, a broad range of graphene materials with different morphologies and properties is available, making the need for an adequate fit between the production method and the desired application even more evident. This review article aims to give the reader a general overview of the recent trends in both the production of graphene and graphene-based materials, and their implementation in different anti-corrosion solutions. Moreover, the present work provides a critical look on this subject, highlighting the areas in need of further exploration.

This paper summarized and collated domestic and foreign literatures on graphene anti-corrosion films and organic anti-corrosion coatings, and formed hierarchical and organized knowledge structures. The preparation, optimization and improvement of graphene anti-corrosion film were reviewed. The corrosion acceleration problems and solutions in the application were discussed. According to the role of graphene in organic anti-corrosion coatings, the improvement of shielding, bonding and self-repairing effect of graphene-based composite materials on organic anti-corrosion coatings are reviewed from the perspective of applied and theoretical research. And the improvement of graphene-based materials on electrochemical protection performance of cathodic-protective organic anti-corrosion coatings are discussed.
