In this work, a fundamental study of ionic liquids (ILs) is shown. The main goal was to establish relationships between rheological and tribological properties of ILs and to understand how these properties are linked to the molecular structure of ILs. Of particular interest were the effects occurring to a frictional system due to variations of the anions and the alkyl chain length of the imidazolium‐based cations. Tribological experiments were performed using a reciprocating ball‐on‐disc test machine. To understand the effects resulting from a variation of the structural characteristics of the used ILs on the rheological properties, studies were performed using a rheometer. The results obtained are very promising in terms of improving friction and wear behaviour by using ILs as lubricants. Copyright © 2012 John Wiley & Sons, Ltd.
