Macroscale liquid superlubricity achieved with mixtures of fructose and diols

Superlubricity has numerous benefits in industrial applications, but its practical applications are restrained from its heavy dependence on special atmosphere environment and the use of low-dimensional materials. This paper reports a novel and facile method to macroscale liquid superlubricity for steel tribopairs, which realizes superlow friction almost right at the start of the test. Two diols of ethylene glycol (EG) and 1,3-propanediol (13-PD)...
