Abstract: Provided herein are processes for the generation of composite polymer materials utilizing a single resin. The processes utilize diffusion between a region undergoing a polymerization reaction preferentially polymerizing one monomer component and an unreactive region. Diffusion and subsequent/concurrent polymerization results in a higher concentration of the more reactive monomer component in the reacting region and a higher concentration of the less reactive monomer components in the unreactive region. The unreactive region may be later polymerized. In embodiments, photopolymerization is used and the regions are generated by a mask or other mechanism to pattern the light.

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.
