<p>PCT No. PCT/EP85/00089 Sec. 371 Date Oct. 28, 1985 Sec. 102(e) Date Oct. 28, 1985 PCT Filed Mar. 8, 1985 PCT Pub. No. WO85/04111 PCT Pub. Date Sep. 26, 1985.A structure usable as an ultrafiltration membrane has membranes (20) with continuous pores which are linked to or into an appropriately porous carrier (21). Each of these membranes (20) consist of protein molecules or protein containing molecules arranged according to a two-dimensional crystal lattice, between which continuous pores of equal size and form remain free, and they are advantageously formed from molecules, which were particularly separated from cell-membranes of procaryons, by means of a recrystallization process designated as self-organization, and which are preferably deposited on or into the carrier (21) and are cross-linked with the carrier (21) intra- or intermolecularly, respectively, through foreign molecules. The structure is suitable, furthermore, for use as a separating organ for a gas separation or for an ion exchange process, as well as for use as a carrier structure for other semi-permeable membranes, such as hyperfiltration membranes. Moreover, with membranes in vesicle form it can serve as a chromatography column and, in the form of film, as envelope material for the most varied substances.</p> |
