IMPROVED POLYMER ELECTROLYTE MEMBRANES FROM MIXED DISPERSIONS

摘要

A polymer electrolyte membrane is provided comprising an intimate mixture of an ionomeric polymer and a structural film-forming polymer. A method of making the polymer electrolyte membrane is also provided, comprising the step of coalescing at least one of an ionomeric polymer and a structural film-forming polymer in a mixture of the two resulting from a mixed dispersion and optionally crosslinking one or both.
