“…Many nanomaterials are beneficial for improving tribological properties of water-based lubricants [6][7][8]. Graphene and graphene oxide [9][10][11], carbon dots [12], hard carbon spheres [13], carbon nanotubes [14], ionic liquids [15], sulfides [16][17][18], oxides [2,7,19], and metal nanocopper [20,21] have been designed and synthesized to improve the performance of water. Furthermore, a number of lubrication mechanisms have been proposed to explain the improvement of tribological performance, including: (a) formation of physical or/and chemical tribofilms.…”

In this study, water soluble CuO nanostructures having nanobelt, nanorod, or spindle morphologies were synthesized using aqueous solutions of Cu(NO 3) 2 3H 2 O and NaOH by adjusting the type of surface modifier and reaction temperature. The effect of morphologies of these various CuO nanostructures as water-based lubricant additives on tribological properties was evaluated on a UMT-2 micro-friction tester, and the mechanisms underlying these properties are discussed. The three different morphologies of CuO nanostructures exhibited excellent friction-reducing and anti-wear properties. Tribological mechanisms differed in the initial stage of frictional interactions, but in the stable stage, a tribochemical reaction film and adsorbed lubricious film on the rubbing surfaces played important roles in hindering direct contact between friction pairs, leading to improved tribological properties.

“…7 Graphene can be validly applied in various elds, such as solar cells, supercapacitors, sensors, thermal conductivity composites and tribological materials. [8][9][10][11][12] When adding graphene into lubricating materials, such as grease, the lubricity of the materials can be enhanced effectively. 13 Besides, compared with the base lubricating material, the thermal conductivity of the composite is also improved.…”

“…Due to a lower thermal conductivity (Table S3, Supporting Information), the increasing friction heat makes EP experience both plastic deformation and plastic flow in the process of friction testing. When the friction force is higher than the shear resistance of the material, the molecular chain of EP is broken, resulting in debris particles on the friction surface . The debris particles are transferred to the steel ball couple surface and form a serious adhesion wear.…”

“…GO can be used in the field of anti‐wear. Similar to other carbon materials, such as carbon black, carbon nanotubes, carbon spheres, or graphite, GO also exhibits superior self‐lubricating effect, causing lower wear rate and lower coefficient of friction (COF) values of the resin based composites …”

materials and epoxy (EP) as matrix through mold pressing, vacuum resin transfer mold (VARTM), and prepreg. GF/EP composites have been widely used in the field of anti-wear composite engineering [4] due to their flexibility, good processability, high specific strength and modulus, low cost, and easy large-scale production, compared to metal and ceramic based ones. [5,6] The friction and wear performance of the material can be further enhanced by incorporating nanoparticles. [7][8][9][10][11] In the organic [12] and inorganic [13] filler systems, carbon-based fillers and metallic oxides, such as graphene oxide (GO) and molybdenum trioxide (MoO 3 ), are often adopted to modify the anti-friction and anti-wear performance of the resin matrix.Due to its superior electrical and mechanical properties, [14,15] GO or reduced GO (rGO) can be used as the additive in the flexible conductive composites [16,17] or lubricating liquids [18] and in the coating film for various composites (such as polyacrylonitrile (PAN), polyethylenimine (PEI), polyphenylene sulfide (PPS), etc.). [19] GO can be used in the field of anti-wear. Similar to other carbon materials, such as carbon black, carbon nanotubes, Antifriction Materials In order to further improve the tribological performance of glass fiber reinforced epoxy (GF/EP) composites, highly flexible, binder-free, molybdenum trioxide MoO 3 nanobelt/graphene oxide (GO) film (f-MoO 3 -GO) is prepared by a hydrothermal method. Herein, f-MoO 3 -GO is adopted to modify GF/EP composites prepared through the vacuum-assisted resin transfer molding method. The neat GF/EP and MoO 3 -GO modified GF/EP composites are also fabricated for comparison. The tribological performance is performed using a ball-on-disc ("steel-on-polymer") configuration under a dry sliding condition. The coefficient of friction is reduced from 0.61 for neat GF/EP composites down to 0.23 for f-MoO 3 -GO modified GF/EP (f-MoO 3 -GO/GF/EP) composites and the anti-wear performance is improved by more than four times. The worn surface morphological observation for the composite samples is used to explain the possible wear micro-mechanisms. The wear reducing effect of the f-MoO 3 -GO/GF/EP composites can be assigned to the increased selflubricating effect of f-MoO 3 -GO. With the combined advantageous properties of the used individual components, these unique composites can be used for many other applications.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.
