Ionic liquids (IL) have shown impressive anti-wear and lubrication properties as compared with common lubrication oils in
general use. ILs are suitable in extremely harsh friction conditions where high thermal stability and chemical inertness is
required. In recent times different type of nanoparticles have gained much attention as anti-wear and extreme pressure additives
to lubrication oils. Reasons behind this phenomenon include the remarkable tribological behavior of nanoparticles even at
severe frictional conditions, and their self-repair capability to the worn surface, and good environmental-friendliness. The aim
of the present study is to covalently functionalize carbon nanotubes (CNT) with IL via esterification reaction and therefore
obtain improved dispersions of CNTs in IL. To the best of our knowledge this is the first report on the direct esterification
of COOH functionalized CNTs with IL, other previously reported methods involve hazardous thionyl chloride and/or more
synthesis steps. Also the applicability of carbon nanotube/IL composites as novel protective lubricating films for metal wear
parts was investigated.
