Abstract

This work reports thermal stability, traction and tribofilm formation properties of three fatty acid-derived ionic liquids (FAILs) and evaluates the influence of the chemical structure of the anion on the properties indicated above. The results indicated that thermal stability of the FAILs is related with the chemical structure of the anion (longer alkyl chain length increases thermal stability and the presence of double bond decreases it). At high temperatures and low speeds, the [N8,8,8,1][C6:0] led to the lowest traction values and the [N8,8,8,1][C18:1] had the highest ones. All FAILs reacted with the steel surfaces creating a tribofilm, that increased with time.
