Abstract
A lubricant, a friction pair having the lubricant and a method for controlling COF between the friction pair are provided. The friction pair includes a first friction part (1) and a second friction part (2). Firstly a lubricant (4) is provided between the first and second friction parts (1, 2). Then a potential is applied on the first friction part (1) via the lubricant (4). And COF is controlled by controlling the potential. The lubricant (4) contains propylene carbonate and a surfactant.
