The disclosure generally relates to omniphobic compatibilizers, which include a polymerization reaction product between a first vinyl monomer, optionally a second vinyl crosslinking monomer, and a functionalized omniphobic polymer. The functionalized omniphobic polymer can include two or more vinyl functional groups or at least one free radical initiator functional group such that the reaction product forming the omniphobic compatibilizer can be a vinyl or free-radical polymerization product. The omniphobic compatibilizer can be incorporated into a UV-curable or a non-UV-curable thermoset omniphobic composition. The UV-curable composition can be a crosslinked polymerization reaction product between the omniphobic compatibilizer, a third vinyl monomer, and a fourth polyvinyl crosslinking monomer. The non-UV-curable composition can be a crosslinked polymerization reaction product between the omniphobic compatibilizer, a first thermosetting component, and a second thermosetting component. The thermoset omniphobic composition can be a coating on a substrate in a corresponding coated article.

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.
