Abstract: This invention concerns the discovery of a new fluid that promotes the fluorination of polymeric materials more safely, more completely, and more efficiently than the fluids used in the prior art. The new fluid is called "dioxifluorine," which is a mixture of carbon dioxide and fluorine where carbon dioxide is the carrier fluid and fluorine is the reactant.
Abstract: The method of treating a surface chemically by exposing the surface to a treating gas at high pressure for a time during which a surface reaction occurs, and then reducing the pressure of the gas for a time and removing reaction byproducts and then continuing the cycles of high pressure and low pressure until the surface reaction is completed.
