Brush polymer coating by in situ polymerization from photoreactive surface

摘要: The invention provides compositions that include crosslinking agents having multiple photoactivatable groups, such as diaryl ketones, or a ketone, benzophenone, and at least one polymerizable monomer, zwitterionic monomer. are useful surface coating provide brush type polymeric coatings. These coatings can be used on medical devices, artificial joints, to reduce wear tear between the components of joint thus eliminate debris generated by friction components.
