Abstract
A method for removing perfluorinated compounds from a fluoropolymer material is provided. The method includes the steps of: (a) providing the fluoropolymer material in a chamber; (b) providing an anaerobic environment in the chamber; and (c) providing a fluorination gas in the chamber, thereby exposing the fluoropolymer material to the fluorination gas. The method results in the removal the perfluorinated compounds from the fluoropolymer material.
