摘要：
Durable, anti-fouling, crosslinked zwitterionic coatings that are grafted to the surface of a substrate through covalent bonding are disclosed. When exposed to a light source, zwitterionic monomers react with a crosslinker and with activated radicals at the surface of the substrate, simultaneously forming the crosslinked zwitterionic coating and anchoring it to the surface of the substrate. Photomasking techniques can be used to micropattern the zwitterionic coatings. The zwitterionic coatings can be applied to a variety of substrates, including medical devices and systems.
