Abstract
Fluoropolymers modified by radio frequency glow discharge in the presence of vapor/gas plasma provides for permanent and controlled substitution of hydrogen and oxygen functionality for fluorine. The oxygen-containing sites of the modified fluoropolymer are highly reactive, enabling the material to be readily refunctionalized by the introduction of a new atom, functionality or macromolecular unit, such as organosilane, alkali metal or reactive fluorescent compound.
