“…To enhance interfacial interactions with the matrix, the surface of MWCNT was functionalized with different functional groups [ 45 , 46 , 47 , 48 ]. Remanan et al functionalized MWCNT with carboxylic group before incorporating it into polyaryletherketone (PAEK) [ 45 ].…”

“…The development of hydrogen bonding between MWCNT and PAEK led to hardness and wear resistance improvement. Polyimide (PI) reinforced by amino-functionalized MWCNT (CNTN) demonstrated a great reduction of COF and WR as compared to pure PI and carboxyl-functionalized nano-molybdenum disulfide (MoS 2 -MA)-reinforced PI [ 46 ]. The incorporation of CNTN converts the adhesive wear of pure PI into fatigue wear, displaying a flat wear surface with cracks caused by shear stress.…”

“…However, in comparison to ZrO 2 , MoS 2 exhibited an inferior effect on wear resistance [ 88 ]. MoS 2 -MA/PI nanocomposites were found inferior compared to CNTN/PI nanocomposites [ 46 ]. However, they are more capable in reducing the fluctuation range of COF values throughout the wear test.…”

“…Another work on surface-modified CNTN/MoS 2 -MA nanohybrid/PI compared the tribological properties of physically (CNT-MoS 2 ) and chemically (CMS) hybridized nanofillers [ 46 ]. CMS/PI demonstrated the lowest COF and WR among all the samples, while CNT-MoS 2 /PI exhibited inferior tribological performance compared to CNTN/PI but superior compared to virgin PI and MoS 2 -MA/PI.…”

Polymer nanocomposites with enhanced performances are becoming a trend in the current research field, overcoming the limitations of bulk polymer and meeting the demands of market and society in tribological applications. Polytetrafluoroethylene, poly(ether ether ketone) and ultrahigh molecular weight polyethylene are the most popular polymers in recent research on tribology. Current work comprehensively reviews recent advancements of polymer nanocomposites in tribology. The influence of different types of nanofiller, such as carbon-based nanofiller, silicon-based nanofiller, metal oxide nanofiller and hybrid nanofiller, on the tribological performance of thermoplastic and thermoset nanocomposites is discussed. Since the tribological properties of polymer nanocomposites are not intrinsic but are dependent on sliding conditions, direct comparison between different types of nanofiller or the same nanofiller of different morphologies and structures is not feasible. Friction and wear rate are normalized to indicate relative improvement by different fillers. Emphasis is given to the effect of nanofiller content and surface modification of nanofillers on friction, wear resistance, wear mechanism and transfer film formation of its nanocomposites. Limitations from the previous works are addressed and future research on tribology of polymer nanocomposites is proposed.

“…In order to improve the tribological properties of lubricating oil further, filling it with different nanomaterials, such as Cu NPs, MoS 2 and GO, is an effective and convenient way. In recent years, more and more layered materials have been used in lubricants, for example, hexagonal boron nitride (H‐BN), MoS 2 , graphite and GO . These researches accelerated the development of new two‐dimensional (2D) lubricating materials.…”

The wet chemical reduction method was used to modify polydopamine (PDA) functionalized oxygenated carbon nitride (O‐g‐C3N4) nanosheets to prepare in situ growth of Cu nanoparticles (Cu NPs) decorated on nanosheets. The PDA attached to the surface of O‐g‐C3N4 provided a uniformly distributed platform for copper nanoparticles. It also provided rich functional groups and provided good conditions for the dispersion of Cu/PDA/O‐g‐C3N4 in pure oil. Through TEM testing, Cu NPs with a diameter of 5–10 nm were evenly distributed on the PDA/O‐g‐C3N4 nanosheets. Through the sliding test on the steel surface, it was obvious that adding 0.2 wt % Cu/PDA/O‐g‐C3N4 to pure oil had a lowest coefficient of friction. In addition, the wear marks on the surface of Cu/PDA/O‐g‐C3N4 steel discs were studied with an optical microscope and a three‐dimensional profiler and its wear resistance was better than Cu NPs, O‐g‐C3N4 and Cu/O‐g‐C3N4.

Multiwalled carbon nanotubes were hydroxylated (MWCNTs-OH) by a strong acid mixture and then used as a reinforcement nanofiller in blends of polytetrafluoroethylene (PTFE) and polyimide (PI) to fabricate MWCNTs-OH/ PTFE/PI nanocomposites. The influences of MWCNTs-OH additions on the surface wettability, tensile mechanical property, and tribological behaviors of MWCNTs-OH/PTFE/PI nanocomposites under different relative humidity were investigated. Test results indicate that the introduction of MWCNTs-OHcan dramatically decrease the static water contact angles and increase the tensile strengths and elastic moduli of the PTFE/PI polymer blends. This is largely due to the existence of numerous hydrophilic functional groups on the surfaces of MWCNTs-OH and its ultrahigh mechanical characteristics. The relative humidity has a much weaker impact on the friction coefficients of the MWCNTs-OH/PTFE/PI nanocomposites than on the wear rates. Of all composites, the 0.8 wt% MWCNTs-OH/PTFE/PI nanocomposite possesses the lowest friction coefficient (0.11) and wear rate (2.97 Â 10 À15 m 3 /(Nm)) at a high relative humidity of 90%. The conspicuous increase in wear resistance is attributable to the enhancement effect of MWCNTs-OH and the generation of homogeneous polymer self-lubricating tribofilms.
