Abstract
A method for the direct fluorination of plastics and articles made from plastics is presented. The novel method includes ensuring extremely low oxygen and moisture content in the chamber before the primary fluorination step, ramping the fluorine concentration during the fluorination step, and providing a quenching step for improved shelf-life. Containers processed by the novel method demonstrate a marked improvement in barrier properties for organic solutions.
