“…44,45 Similar results of enhanced tribological properties from the synergistic effect of various nanofillers were also reported elsewhere. 46 Xie prepared a novel carbon sphere@1T-MoS 2 hybrid as a facile lubricant additive of polyethylene glycol 200. 47 The results indicated that the COF of pure PEG200 oil decreased by 43% with the introduction of 0.31 wt% CS@1T-MoS 2 , suggesting the synergy between CS and 1T-MoS 2 played a vital role in the antifriction and wear resistance.…”

Epoxy composites with simultaneously enhanced tribological and mechanical properties filled with basalt belt/reduced graphene oxide/paraffin wax (EP/BF/RGO/PW) have been successfully prepared. Experimental results indicated that the mechanical property of the composites was reinforced by basalt belt, and the tribological property was greatly improved by reduced graphene oxide/paraffin wax at the same time. Thanks to the synergy of PW and RGO sheets, the optimized coefficient of friction and wear rate of the composite declined by 77.5% and 14.4% than pure EP under dry friction conditions of 60 N and 0.42 m s−1. In comparison to pure EP, the tensile strength and modulus of the optimized composite increased by 75.5% and 100% on account of the robust basalt fibers. Thus, the combination of basalt fiber and reduced graphene oxide/paraffin wax can readily realize the introduction of enhancer and oil‐impregnation in EP, offering a promising approach for simultaneously improving the mechanical and tribological properties of epoxy.Highlights A novel BF/RGO/PW 3D skeleton was developed via a facile hydrothermal method. The BF/RGO/PW can enhance the mechanical and tribological properties of EP. The basalt fibers account for the improvement in mechanical property. A reduction of 77.5% in COF and a decrease of 14.4% in wear rate were realized.

“…Of course, various types of additives in the lubricating system have distinct interaction forces on the interfacial behavior, such as the van der Waals force, physical and/or chemical adsorption, coordination, or hydrogen bonding. − Among them, the common materials mainly include nanomaterials, − hybrid materials, , gel, functional modification materials, , covalent/metal–organic framework materials, , ionic liquids (ILs) , , deep eutectic solvent, etc. Based on highly designable molecular structures and tunable properties characteristic, highly polar ILs are superior in competitive adsorption for polyethylene glycol base systems, laying the foundation for the lubricating system with high-performance, multifunctional properties, and service stability .…”

As a hydrophilic polyether molecule, polyethylene glycol has environmentally friendly, degradable, and compatibility characteristics, gradually becoming a potential choice for green lubrication. Two novel multifunctional protic ionic liquids (ILs) were synthesized, and an ILs-PEG200 lubrication system was constructed with a strong hydrogen bonding network structure. The determination of rheological properties and boundary lubrication states inspired us to consider the interaction between polar additives and systems. Surprisingly, an extremely stable run-in period was obtained by the high efficiency adsorption contributed from high-polarity ILs at the sliding interface in the initial shear stage. Meanwhile, the ILs-PEG200 lubrication system also has superior load carrying and antishear properties, as well as remarkable lubrication stability even under very high loads, showing certain potential for engineering applications. In addition, the lubrication mechanism was obtained by exploring the interaction among ILs, PEG system, and metal surface, and the results revealed that tribo-oxidation reactions, physical/chemical adsorption, and tribochemical reactions occurred on the metal asperity during shear. Therefore, a tribofilm containing metal phosphates and sulfides is generated through the occurrence of tribochemical reaction and the synergistic effect of the base system, metal interface, and functional additives. The protic ILs lubrication additives in this work can significantly enhance the tribological performance of poly(ethylene glycol) systems under harsh conditions, providing a theoretical basis for its development in the engineering field.
