“…The first article on IL lubricant systems, HexMeImBF 4 and HexEtImBF 4 , has been published by Liu et al [44,45] Tribological tests of several frictional pairs, such as steel/steel, steel/Al, steel/Cu, and Si 3 N 4 /SiO 2 , gave surprising results in that the ILs have a friction reduction and anti-wear performance that were superior to those obtained for widely used fluorine-containing lubricants. This result urged further tribological investigation using IL-based systems.…”

Ionic liquids (ILs) including ambient-temperature molten salts, which exist in the liquid state even at room temperature, have a long research history. However, their applications were once limited because ILs were considered as highly moisture-sensitive solvents that should be handled in a glove box. After the first synthesis of moisture-stable ILs in 1992, their unique physicochemical properties became known in all scientific fields. ILs are composed solely of ions and exhibit several specific liquid-like properties, e.g., some ILs enable dissolution of insoluble bio-related materials and the use as tailor-made lubricants in industrial applications under extreme physicochemical conditions. Hybridization of ILs and other materials provides quasi-solid materials, which can be used to fabricate highly functional devices. ILs are also used as reaction media for electrochemical and chemical synthesis of nanomaterials. In addition, the negligible vapor pressure of ILs allows the fabrication of electrochemical devices that are operated under ambient conditions, and many liquid-vacuum technologies, such as X-ray photoelectron spectroscopy (XPS) analysis of liquids, electron microscopy of liquids, and sputtering and physical vapor deposition onto liquids. In this article, we review recent studies on ILs that are employed as functional advanced materials, advanced mediums for materials production, and components for preparing highly functional materials.

“…A lot of researches have been published concerning the use of ionic liquids as lubricants since 2001 [29], proving their remarkable potential for this purpose [4,6,[30][31][32]. At the beginning, imidazolium-based ionic liquids with [PF 6 ] and [BF 4 ] anions were widely used [33][34][35]. Despite their good tribological behaviour, the hydrolysis products of those anions are highly corrosive [36].…”

Isoconversional kinetic analysis applied to five phosphonium cation-based ionic liquids

Thermal degradation of five phosphonium cation-based ionic liquids ([P 66614 outperforming the other ones in both pyrolytic and oxidising conditions. Although the thermal degradation mechanism is affected by atmospheric conditions, the degradation trend remains practically constant. As the dynamic methodology usually overestimates the long-term thermal stability, an isoconversional methodology is better for predicting the long-term thermal stability of these ionic liquids in order to be used as base oil or additive in lubricants formulation. Finally, the model-free methodology can predict at lower costs the ILs performance in isothermal conditions. Highlights• Weakly coordinating anions provoke good thermal stability of ILs.• • Isoconversional methods are better than dynamic ones for long-term thermal studies.• Activation energy behavior at low conversions is related to a single reaction.• Model-free methodology can predict the ILs performance in isothermal conditions.

“…[14] Ionic liquids with the hexafluorophosphate anion have been evaluated extensively using conventional friction and wear tests and were found to exhibit improved friction and wear properties compared to conventional lubricants. [21,[23][24][25] The ionic liquid containing the octyl sulfate anion has been developed more recently and is of interest due to its resistance to hydrolysis. [14] Based on these findings, the ionic liquids of interest in this study are 1-butyl-3-methylimidazolium hexafluorophosphate (BMIM-PF 6 ) and 1-butyl-3-methylimidazolium octyl sulfate (BMIM-OctSO 4 ).…”

Ultrathin Wear‐Resistant Ionic Liquid Films for Novel MEMS/NEMS Applications

2008

View full text Add to dashboard Cite

Two ionic liquids, BMIM‐PF6 and BMIM‐OctSO4, are applied on Si (100) and investigated for the first time using atomic force microscopy (AFM). These liquids exhibit comparable adhesion, friction and wear characteristics relative to the perfluoropolyether lubricant Z‐TETRAOL. By configuring the AFM as a nano‐Kelvin probe, surface potential maps of the coated surfaces are obtained after wear testing.
