ASYMMETRIC POLYMER FILM, METHOD FOR THE PRODUCTION AND THE UTILIZATION THEREOF

摘要

The invention relates to an asymmetric polymer film, particularly based on polyazoles, to a method for the production of said polymer film and to the utilization thereof. The polyazole-based asymmetric polymer film according to the invention has a smooth and a rough side and enables rapid and homogenous doping with acids in order to form a proton-conducting membrane due to its asymmetric structure. The inventive asymmetric polyazole-based polymer film can be used in a variety of ways due to its outstanding chemical, thermal and mechanical properties and is particularly suitable for the production of polymer electrolyte membranes (PEM) for so-called PEM fuel cells.
