Structure with membranes having pores extending throughout, process for producing this structure and its uses

Abstract

Abstract A structure which can be used as an ultrafiltration membrane has membranes (20) with penetrating carrier pores, which are bound to or bound into a support (21) which may be porous. These membranes (20) each consist of protein molecules or protein-containing molecules which are arranged in the manner of a two-dimensional crystal lattice and between which penetrating pores of identical size and shape having pore diameters especially between 1 and 8 nm remain free, and are in each case advantageously formed from molecules, which were separated off especially from cell walls of prokaryotes, by a recrystallisation process described as self-organisation and preferably flushed onto or into the carrier (21) and crosslinked intramolecularly or intermolecularly or to the carrier (21) by extraneous molecules. The structure is also suitable as a separation element for a gas separation or for an ion exchange process and also as a carrier structure for other semipermeable membranes such as hyperfiltration membranes. It can also be used with membranes in a vesicular form as a chromatography column or in film form as a wrapping material for the most diverse substances. <IMAGE>
