Fluorinated graphene oxide nanosheet: A highly efficient water-based lubricated additive

Influence of fluorinated graphene-modified epoxy coatings on the corrosion behaviour of 2024 aluminium alloy

“…Raman spectroscopy is commonly used to characterise variations in the degree of defects in graphene materials. 14 As shown in Fig. 5, graphite, GO, FG1 and FG2 samples exhibit characteristic diffraction peaks at both the D band (1360 cm À1 ) and the G band (1580 cm À1 ).…”

“…Some of its advantages are large surface area, wide band gap, high stability, low surface energy and hydrophobicity, in addition to its graphene-like twodimensional lamellar structure. [4][5][6][7] These advantages set FG apart for application as a new type of carbon material in thin high performance dielectric materials, [8][9][10][11] thermoelectric devices, 6,12 lubrication, [13][14][15] nano-composite materials, 16,17 and even stem cell substrates. 18 Despite all the successes on its utilization in a wide range of industrial applications, scanty reports exist on its research in the eld of anticorrosion, especially organic coatings.…”

High mechanical and tribological performance of polyimide nanocomposite reinforced by fluorinated graphene oxide

“…Subsequently, 0.5 mL of HNO 3 and 9.5 mL of HF were sequentially dropped into the suspension and then the mixture was shifted to the Teflon‐lined stainless steel autoclave, followed by heating at 160°C for 12 hours. Finally, the FGO powders were obtained directly via evaporating the above solution . Additionally, aforementioned approach is a simultaneous fluorination and reduction process, so the reduced graphene oxide (rGO) was synthesized with GO (50 mg) and deionized water (50 mL) by the same process for comparation.…”

A Comprehensive Review of Water-Based Nanolubricants

“…The as-prepared GO nanosheets (0.5 mg/mL) were dispersed in water by bath ultrasonication, which resulted in no sedimentation for 5 weeks. After obtaining GO from Hummers' method, min et al [72] prepared fluorinated GO (FGO) through 12 h hydrothermal treatment at 160 • C with the presence of 0.5 mL nitric acid and 9.5 mL hydrofluoric acid. The produced FGO was dispersed in water with 0.1-1% concentration by ultrasonication, and the as-prepared lubricants exhibited excellent stability for 12 days.…”

“…It has been proved that the corrosion resistance of water can be enhanced by adding water-soluble additives. For example, nanoadditives such as fluorinated graphene [72], surface-modified CuS NPs [62], and GO-TiO 2 [84] are able to retard the corrosion of steel by forming a protective film on the steel surface. Corrosion inhibitors such as Triethanolamine (TEA) [92] and sodium dodecyl benzene sulfonate (SDBS) [63], have also been used to minimise the corrosivity of water-based lubricants.…”
