“…Figure 7 shows the influence of the filling content of CNTs or nano-capsules on the COF and WR of PEEK at a load of 50 N and a sliding speed of 0.5 m/s. In Figure 7a, the lower content of CNTs leads to a certain diminution of the COF of PEEK, which is due to the molecular structure of the CNTs being destroyed during friction, and the adsorption and sedimentation of the CNT' molecular fragments may produce certain an anti-friction effect [41]. Then, the CNTs content exceeded 4% and continued to rise, the anti-friction effect of PEEK/CNTs became less significant, as excess CNTs might act as a deterrent.…”

Polyether-ether-ketone (PEEK) exhibits great potential in being a replacement for metal components across various applications relying on the mechanical and tribological properties. However, there is still much to be done to improve its properties. The main motivation of this paper is to improve the tribological and mechanical properties of PEEK simultaneously for more severe working environment. Therefore, dialkyl pentasulfide (RC2540) was proposed to fill into the cavity of CNTs to prepare nano-capsules, which were then filled into PEEK to prepare PEEK/nano-capsules composites. The existence of nano-capsules in PEEK was analyzed, and the friction and wear properties exhibited by PEEK composites against GCr15 steel were examined using pin-disk friction pairs, and the self-lubricating mechanism of PEEK composites in friction was revealed. Findings of this study indicated that when the mass fraction of nano-capsules was less than 5%, the filling of nano-capsules could improve the tensile strength of PEEK and reduced the friction coefficient and specific wear rate of PEEK by filling nano-capsules. During the friction process, RC2540 in the nano-capsules can be released as PEEK wears so that a self-lubricating layer can be formed for reducing PEEK composites’ friction and wear.

“…The application of GO in heterocyclic polymer also has raised concerns. Yin et al [113] compared the different performance of polyetheretherketone (PEEK)/GO under water lubrication or PEEK lubricated by GO aqueous solution. The GO aqueous solution decreased the COF and wear by 55% and 94%, respectively, versus pure water.…”

Water is as an economic, eco-friendly, and efficient lubricant that has gained widespread attention for manufacturing. Using graphene oxide (GO)-based materials can improve the lubricant efficacy of water lubrication due to their outstanding mechanical properties, water dispersibility, and broad application scenarios. In this review, we offer a brief introduction about the background of water lubrication and GO. Subsequently, the synthesis, structure, and lubrication theory of GO are analyzed. Particular attention is focused on the relationship between pH, concentration, and lubrication efficacy when discussing the tribology behaviors of pristine GO. By compounding or reacting GO with various modifiers, amounts of GO-composites are synthesized and applied as lubricant additives or into frictional pairs for different usage scenarios. These various strategies of GO-composite generate interesting effects on the tribology behaviors. Several application cases of GO-based materials are described in water lubrication, including metal processing and bio-lubrication. The advantages and drawbacks of GO-composites are then discussed. The development of GO-based materials for water lubrication is described including some challenges.

“…[19][20][21] Besides, lots of unlubricated polymer resins such as polyimide (PI) have low modulus and bearing capacity, which are limited to be applied in harsh conditions (e.g., superhigh vacuum, humid). [22][23][24][25] Therefore, the modification of polymer resins improved by lubricants is a key to solving poor lubrication problems. It is worth noting that polymer lubricants are widely used in aerospace, public transportation, and microelectronics due to their lightweight, low price, good self-lubricating, and adjustable structure.…”

Solid lubricant materials could be used in various extreme conditions owing to the excellent anti‐friction and ‐wear with the low friction coefficient and wear rate. Polyurethane (PU)‐based solid lubricants as one of the widely utilized composite materials had been well‐known by researchers all over the world. PU‐based composite lubricants were commonly segmented into single‐phase lubricants and multi‐phase lubricants via inorganic or organic lubricant additives. What is more, the modified PU by solid lubricants would endow higher tribological performances than that of single‐phase PU‐based lubricants. Based on the multi‐component synergy, the multi‐phase lubricants could significantly improve the PU matrix's lubrication and wear resistance and enhance the comprehensive performance such as corrosion resistance. This paper mainly discussed and summarized the recent development in tribological performances of PU‐based composite lubricants, and explored their prospective research directions.
