Abstract锛�Water-lubricated bearings are widely used in marine propulsion systems, water turbines, water pumps and other fields due to their green, pollution-free, energy-saving and environmental protection characteristics. The performances of polymer bearing materials directly affect the stability of mechanical operation. Firstly, the characteristics of water as lubricant are introduced, and the advantages and disadvantages of commonly used polymer bearing materials are compared. Then, in response to the problems of insufficient tribological properties of polymer materials during practical use, the polymer blending methods are introduced first, and then according to different mechanisms of action, the research progress on improving tribological properties of polymer materials by modifying water lubricated polymer bearing materials is reviewed from three aspects: improving mechanical properties, enhancing lubrication effects and synergistic effects of the two. Finally, the future key research directions are prospected for material modification of water lubricated polymer bearings.
