英文摘要： High contact resistance, friction and wear, corrosion are common problems that restrict the quality and service life of space technology, national defense industry and other large equipment, micro/nano electromechanical systems. Therefore, developing high performance，no corrosion ionic liquid conductive lubricating greases and finding the tribological rules and friction reduction and antiwear mechanisms of them is one of the hot and important topics in the field of tribology. The ionic liquid molecular design and interface chemistry as the guiding ideology and considering the high temperature resistant bisimidazolium, oil soluble quaternary phosphonium and new lithium ionic liquid, this project will use polytetrafluoroethylene as thickener to controllably prepare the high performance and corrosion free ionic liquid lubricating greases, carry out research on the molecular structure of ionic liquid lubricating greases and their tribological rules under electric field condition, reveal the lubrication and anti-wear mechanism of conductive ionic liquid lubricating greases, build the molecules tailored design theory of high performance conductive ionic liquid lubricating grease.
