“…The results indicated that the corrosion currents of the CNT- and graphene-modified carbon felt electrodes were 1.07 × 10 −7 and 2.95 × 10 −6 A, respectively. Owing to the outstanding conductivity of graphene, a path for electrochemical reactions was provided; consequently, the corrosion current of the graphene-modified carbon felt electrode was higher than that of the CNT-modified carbon felt electrode [29]. However, the currents of both the modified electrodes were higher than the 5.75 × 10 −6 A current of the unmodified carbon felt electrode.…”

The electro-Fenton system has the ability to degrade wastewater and has received attention from many researchers. Currently, the core development objective is to effectively increase the degraded wastewater decolorization efficiency in the system. In this study, to improve the electro-Fenton system reaction rate and overall electrical properties, we used polyvinylidene difluoride to fix carbon nanotubes (CNTs) and graphene onto the system cathode (carbon felt electrode), which was then used to process Reactive Black 5 wastewater. Furthermore, we (1) used scanning electron microscopy to observe the structural changes in the electrode surface after modification; (2) used the Tafel curve to determine the electrode corrosion voltage and corrosion rate; and (3) analyzed the azo-dye decolorization level. The results showed that the maximum system decolorization rates of the CNT- and graphene-modified carbon felt electrodes were 55.3% and 70.1%, respectively. These rates were, respectively, 1.2 and 1.5 times higher than that of the unmodified carbon felt electrode, implying that we successfully improved the cathode characteristics. The modified electrode exhibited an improved conductivity and corrosion resistance, which, in turn, improved the system decolorization efficiency. This significantly increased the electro-Fenton system overall efficacy, making it valuable for future applications.

“…The positive reinforcing effect of rGO on improving corrosion resistance has been proved in different studies including research by Tamilarasan et al [22], who reported improved corrosion and erosioncorrosion behavior of electroless nickel-phosphorous coatings on low carbon steel caused by adding rGO particles. Jang et al [23], prepared rGO protection layer on aluminum using the immersion method with the aid of polyvinyl alcohol, which is resulted in the higher corrosion resistance of the coatings.…”

“…The morphology, composition, crystal structure and hardness of the coatings were also analyzed. Inspired by some hydrophobic biological surfaces in nature (Tamilarasan T R, et al 2017), Biomimetic hydrophobic graphene coatings successfully prepared on Al alloy substrates (Zheng et al 2016); (Xue et al 2016) successfully synthesized for aluminum alloys Corroded graphene films; Long-term corrosion protection of steels was studied to use in chloride environments such as seawater (Raghupathy et al 2017); The effect of reduced graphene oxide (RGO) and molybdenum on the corrosion resistance of bipolar plate amorphous nickel phosphorus (Ni-P) in proton exchange membrane fuel cells was discussed in (PEMFC) (Lv et al 2016).…”

Graphene has been applied and demonstrates its excellent functions in various functional coatings by virtue of its excellent thermal, mechanical and electrical properties. This paper mainly introduces the application status and effect of graphene in conductive coating, anticorrosive coating, flame retardant coating, thermal conductive coating and high-strength coating. Finally, the application prospect of graphene in the field of coating is prospected.
