Background
Energy conservation and consumption reduction are key problems which need to be solved urgently in the industry at present, and about one third of the total energy consumption in the world comes from friction-related consumption. The energy consumption of macroscopic friction is essentially the accumulation of various energy consumption of microscopic friction. Solid ultra-lubricity is an effective method for reducing friction and energy consumption under the micro-nano scale. The two-dimensional material becomes a leading-edge hotspot of the research in the solid ultra-smooth field due to the characteristics of atomic-level thickness, smooth surface, excellent performance, controllable defects and the like. Accurately representing the friction energy consumption value of the two-dimensional material, and is one of the key steps of energy conservation and consumption reduction. Meanwhile, friction causes a relatively high temperature in an interface adhesion area, when the interface temperature changes, the equilibrium state is destroyed due to local heat generation, the occupied number of phonons on each energy level also changes, and the phonons are dissipated in a mutual collision manner, so that a non-thermal equilibrium state is converted into an equilibrium state. Phonon dominated friction-to-heat conversion is the primary route to frictional energy consumption, and both phonon frequency and phonon lifetime influence the rate at which frictional energy consumption processes occur. Therefore, phonon dynamic characteristics in the friction process are accurately detected and represented, the influence rule of phonons on the friction energy consumption of the two-dimensional material is obtained, the origin of friction is explored from the energy consumption perspective, the ultra-smooth nature is understood, and finally the friction energy consumption is regulated and controlled to achieve the purposes of reducing friction and reducing consumption.
