  • Patent number: 11384213
    Abstract: Methods for modification of surface wettability of fluorine-containing polymers by sequential treatments first with gaseous plasma rich in ultraviolet radiation, and then oxidation using neutral reactive oxidative species. The methods are rapid and permit treatment of fluorine-containing polymers of any shape and size including ‘infinite’ materials such as foils. A surface layer of an object made from a fluorine-containing polymer is depleted of fluorine upon interaction with gaseous plasma rich in ultraviolet radiation. The depleted surface layer is then exposed to reactive oxygen species such as neutral oxygen atoms in the ground state. The wettability of objects made from or containing fluorine-containing polymers treated according to the methods of the present disclosure is close to the theoretical limit for smooth polymers well functionalized with polar functional groups.
