CERAMIC MEMBRANE BASED ON A SUBSTRATE CONTAINING POLYMER OR NATURAL FIBRES, METHOD FOR THE PRODUCTION AND USE THEREOF

摘要

The invention relates to membranes and a method for the production thereof. The inventive membranes are characterised in that they comprise a flat flexible substrate provided with a plurality of openings and a coating arranged on the inside and outside of said substrate. The material of the substrate is selected from non-woven made of polymer fibres having a porosity of more than 50 % and the coating is a porous, ceramic coating. Preferably, the substrate has a thickness of between 10 - 200 ñm. Said membranes have a visibly higher flow than traditional membranes. The membranes can be used as separators for batteries or as microfiltration membranes.
