Abstract
The present invention relates to a membrane comprising a flat, flexible substrate having a plurality of openings and having a porous inorganic coating situated on and in said substrate, the material of the substrate being selected from woven or non-woven, electrically non-conductive fibers, characterized in that the substrate comprises polyaramide fibers that are pure or connected to fibers of the further polymer or at least of one of these further polymers, wherein the fibers of at least one of said further polymers comprise a melting point that is lower than the decomposition point of the polyaramide fibers.
