Abstract

Ionic liquid (IL) can be used as external or internal lubricant. The tribological performance of polyimide (PI)–steel contact surface driven by IL lubricant was investigated using a ball-on-disk tribometer in high-vacuum environment. The experimental results indicated that IL as the external lubricant could obviously decrease the friction coefficient of PI from 0.41 to 0.01 and corrode the surface of steel ball. As internal lubricant, some IL/PI composite films were prepared, and the structure properties and tribological behavior were investigated. IL can be uniformly dispersed in the polymer and could make film surface more hydrophilic along with the increasing content of IL in PI. The IL/PI composite film with 1% content of IL has the lowest friction coefficient and causes the least damage against the steel ball.
