Keynote address: Synthetic lubricants: mechanisms from molecular level to macroscale
Lubrication is an important technical means of energy conservation and emission reduction, a technical way to ensure the smooth and effective operation of machinery. The machine elements that require lubrication to secure operation of machnieries including bearing, gear, hydraulic components etc. Therefore, it has important applications in the civilian military industry. Lubrication is an important part of tribological research. Friction occurs at the solid-solid interface, and the friction process is accompanied by physicochemical processes. Under liquid lubrication conditions, the physical and chemical properties of lubricating oil (viscosity, viscosity index) and its interaction with the interface (adsorption, assembly, destruction) determine its lubricating properties. On the solid surface, molecular adsorption and assembly are the main working principles of lubricants under boundary lubrication conditions, and the strength and density of adsorption affect the friction and anti-wear and bearing capacity of the lubricant. The report describes how simple interface assembly chemistry and supramolecular assembly guide the design of lubricant molecules and play an important role in lubrication. The principle of assembly chemistry can be used to further optimize the molecular structure, improve its lubrication and anti-wear performance, and design novel functional greases. Tribological research methods also provide useful assistance in understanding the dynamic processes of interface assembly chemistry (formation and destruction of assemblies).
