GETRÄGERTE METALLMEMBRAN, VERFAHREN ZU IHRER HERSTELLUNG UND VERWENDUNG

摘要

Metal membrane contains a metal membrane formed on a supporting surface of a porous membrane carrier. The pores of the membrane carrier are closed in the region of the supporting surface using an auxiliary material before applying the metal membrane and opened after applying the metal membrane by removing the auxiliary material. An independent claim is also included for a process for the production of the metal membrane comprising filling the pores of the membrane carrier using the auxiliary material, polishing and purifying the supporting surface, applying the membrane on the supporting surface, and removing the auxiliary material from the pores of the carrier.
