Physicochemical and tribological properties of copyright-type halogen-free dicationic ionic liquids
Abstract A series of new halogen-free dicationic ionic liquids (ILs) with different alkyl chain lengths were prepared, and the relationship between the alkyl chain length, physicochemical and tribological properties of ILs, and their role as neat lubricant for steel-steel friction pairs, was investigated.Evaluation of stability during hydrolysis an
