Abstract: This paper briefly reviews four main research directions of lubrication discipline, as biomimetic hydrophilic lubrication, biomimetic lubrication drag-reduction, solid lubricant materials & technology, and liquid lubricants. We summarize the international frontiers, domestic research situation, existing problems and future development trends for each direction. The suggested research contents in future are as follows:(1) After Studying the relationship between interface hydration and lubrication along with its regulation mechanism, aim to developing biomimetic hydrophilic lubrication materials with high load bearing, low friction & anti-wear properties, and key wa-ter-lubricating coating technologies suitable for modification of high-end implanted biomedical devices, by using innovative design ideas such as layering, gradient and soft & hard composition; (2) After studying on the relationship between interface wetting and drag reduction along with its regulation mechanism, aim to developing effective gas-film stabilization technology on super-hydrophobic surfaces and elastic drag-reduction technology on super-hydrophilic surfaces to achieve efficient drag-reduction under turbulent flow condition by the bionic design of surface structures and components; (3) Applying the concept of supramolecular assembly to design new liquid lubricants and study its interaction mechanism, aim to developing new liquid lubricants with anti-irradiation, anti-aging, anti-climbing, anti-corrosion, environ-ment friendly and reusable characteristics, by precisely designing molecular structures and controlling the preparation technique; (4) Developing solid lubrication materials with excellent friction-reduction, anti-wear, long serving-lifetime, radiation resistance, corrosion resistance, strain resistance and wide temperature-range adaptation characteristics, by adopting novel concepts of surface and interface physichemistry, such as layered, soft/hard composition, multi-component coupling, gradient and in situ healing.
