Room temperature ionic liquids (RTILs) have been attracting significant and growing interest as the lubricants, owing to their intrinsic useful properties such as good thermal stability, negligible vapor pressure, good low temperature properties, good flame retardant properties. In this study, several imidazolium-based ionic liquids, 3-alkyl-1-alkylimidazolium tetrafluoroborates, hexafluorophosphonates, trifluoromethane sulfonates, and bis(trifluoromethanesulfoimide), were synthesized. The physical properties of synthetic RTILs such as kinematic viscosity, RI, thermal properties were evaluated and their tribological behaviors of 4-ball WSD and friction properties as the lubricants were evaluated.
