Outline of Final Research Achievements

We attempted to control the friction behavior by changing the interfacial abundance ratio of anions and cations constituting an ionic liquid by applying an electric field between solid surfaces under the ionic liquid lubricating condition. As a result, it was clarified that the controllability varies depending on the magnitude and structure of anions and cations, and the magnitude of the electric interaction force between anion and cation. We used ionic liquid as bulk lubricant and succeeded in doubling the coefficient of friction by application of electric field in macroscopic friction between flat plates. However, the low friction phenomenon, which has been reported in the previous research in the micro-tribology, was not confirmed in our set up. It is considered that the optimization of ion species and sliding morphology is necessary to develop friction reduction effect.
