Abstract

The guanidinium ionic liquids (GILs) are synthesized and have better thermal stability than perfluoropolyether (PFPE) and 1-hexyl-3-methylimidazolium bis(trifluoromethyl sulfony)imide (LF106) according to thermogravimetric analysis. GILs possess better antifriction and antiwear performance in wide temperature range (from RT to 300 °C) than PFPE and LF106. Meanwhile, GILs have the smaller weight loss and still perform good lubricating property after the treatment of high-temperature. Then, energy dispersive spectrometer (EDS), corrosion, electrochemical and quartz crystal monitor tests are carried out to investigate the influence of adsorbability of cations to the lubricating property of GILs and LF106 under different temperature conditions.
