The aging population necessitates a critical need for medical devices, where polymers-based surface lubrication coating is essential optimal functionality. In fact, and mechanical requirements vary depending on the service environment of different devices. Until now, key mean still blank general preparation hydrophilic coatings with on-demand mechanics lubricity. This study introduces novel tunable properties lubricity, derived from eco-friendly polymerizable deep eutectic solvents (PDESs) containing betaine, hydroxyethyl acrylate, glycerol, tannic acid. Unlike traditional high molecular weight polymers, this approach leverages small-molecule, high-biobased PDESs, thereby simplifying synthesis process. resulting demonstrates exceptional adhesion to range device materials─including glass, stainless steel, polyvinyl chloride, polyurethane─thanks content hydroxyl groups pyrogallol motifs It also enables precise tuning strength, modulus, adhesion, hydrophilicity, by varying amounts glycerol Furthermore, undergoes hydration-induced transition high-strength, high-friction low-strength, low-friction states, maintaining repeatable performance. Additionally, synergistic effects betaine acid in PDES contribute its notable antimicrobial properties. summary, these PDESs demonstrate significant potential enhancing biomedical
