Special Issue Information

Dear Colleagues,

The development of room temperature ionic liquids (RTIL’s—also known as room temperature molten salts) as multi-purpose chemical tools has been phenomenal since 2000. The scientific literature has steadily increased to the point where thousands of new articles are produced by scientists world-wide every year. In the early days of RTIL development, these chemical systems were used primarily as chemical reaction media (quite successfully) and as a host for various electrochemical studies. Ionic liquids are generally described as “green systems” due to the recycling of these host systems in which a variety of chemical reactions can be run.

Many new RTIL’s are reported each year and cover a wide selection of chemical characteristics that include either hydrophobic or hydrophilic properties over wide temperature ranges. Mass spectrum studies have shown the ability of RTIL’s to form large aggregates even in the gas phase. This polymeric characteristic of RTIL’s is readily explained through spectroscopic evidence and theoretical studies in which coulombic interactions, hydrogen bonds, van der Waals and other forces provide the “glue” that holds these aggregates together. This type of stability is extremely advantageous and in many cases can be engineered for a specific application.

The application in question is the ability of RTIL’s to act as lubricants on a variety of metallic and non-metallic surfaces. RTIL’s are excellent candidates for such a task as they are often excellent at heat dissipation and can be engineered to lubricate a specific surface. In recent years the scientific community has devoted itself to the testing and development of potential RTIL lubricants. It is my hope that this special issue will provide an additional catalyst for the advancement of ionic liquid tribology.

Due to ever increasing demands on lubricants, such as increased service intervals, reduced volumes and reduced emissions, there is a need to develop new lubricants and improved wear additives. Ionic liquids (ILs) are room temperature molten salts that have recently been shown to offer many advantages in this area. The application of ILs as lubricants in a diverse range of systems has found that these materials can show remarkable protection against wear and significantly reduce friction in the neat state. Recently, some researchers have shown that a small family of ILs can also be incorporated into non-polar base oils, replacing traditional anti-wear additives, with excellent performance of the neat IL being maintained. ILs consist of large asymmetrical ions that may readily adsorb onto a metal surface and produce a thin, protective film under boundary lubrication conditions. Under extreme pressure conditions, certain IL compounds can also react to form a protective tribofilm, in particular when fluorine, phosphorus or boron atoms are present in the constituent ions.
