The medical catheters are essential consumables widely used in various surgical operations and intubation operations. The super-lubricant polymer coatings on the surface of medical catheters can reduce the tissue friction of the catheter in clinical applications and avoid tissue damage and inflammation. This review summarizes the research of different polymer super-lubricant coating systems

coating adhesion optimization and antibacterial modification

and introduces the research progress of polymer super-lubricating coating systems such as polyvinylpyrrolidone

polyacrylamide

polyethylene glycol

natural polysaccharide and derivatives

as well as the method of improving the coating adhesion with silane coupling agent and photochemical reaction

and the latest research on the antibacterial modification of hydrophilic coating by inorganic antibacterial agent

organic antibacterial agent and drug loaded coating.
