The process of plasma induced crosslinking involves a physical or chemical reaction that breaks chemical bonds on the surface of the material. The resulting radicals in the polymer chain react with adjoining chains linking one polymer chain to another which improves the surface’s barrier and biocompatibility characteristics. It is also a means to remove weakly bonded species from the surface of materials. Some surfaces can be effectively sealed with this process. Sealing reduces the potential for gases or liquids to penetrate into the surface and/or it also prevents internal mobile species from migrating to the surface or blooming.
