Mikroporöse Membran mit einer Polymermatrix sowie Verfahren zu deren Herstellung

摘要

The invention relates to a microporous membrane with a polymeric matrix consisting of a polymer that can form hydrogen bridge-type bonds. Said membrane is characterized in that at least one inorganic filling material is distributed in the polymeric matrix. the porous structure of the membrane is preserved with the admixture of filling material even when it is dried in a conventional manner, e.g. in an air current. Said membrane can be directly used as a porous membrane for separating liquid, gaseous or vaporous mixtures, as supporting membrane for catalytic membranes and as supporting membrane for composite membranes.
