AI Technical Summary
Existing medical devices with hydrophilic coatings face challenges in achieving sufficient adhesion, particularly when using epoxy resin on metal or urethane surfaces, necessitating additional layers and complex structures to enhance adhesion.
A hydrophilic coating film composed of a copolymer with crosslinked polymerization units having hydrophilic structures, utilizing a crosslinking mechanism that includes betaine, amide, or lactam structures, and a catalyst-like quaternary ammonium group to simplify the coating process and improve adhesion.
The solution enhances adhesion and hydrophilicity of the coating film on medical devices, providing a simpler and more effective hydrophilic coating method with improved biocompatibility and lubricity.
