Abstract
Composite film articles and assemblies that include at least one layer of expanded fluoropolymer bonded to at least one thermoplastic sheet are fabricated using a method which can adjust the gas and liquid permeability of the composite film assemblies. These composite film articles and assemblies optionally have electroactive properties and a thin porous metallic overlayer that can serve as a current collector, and can be used in electrochemical devices such as air depolarized cells.
