The invention relates to a membrane that consists of a polymer or a polymer mixture. The aim of the invention is to produce membranes, especially planar membranes or hollow fiber membranes that have an as high a separation efficiency as possible while simultaneously having a high membrane efficiency. To this end, the membrane has a gas- or liquid-permeable bicontinuous foam structure with orifices in the interior whose diameters do not exceed 500 nm.
