Abstract

Synthetic membranes for the removal, isolation, or purification of substances from a liquid. The membranes include at least one hydrophobic polymer and at least one hydrophilic polymer. 5-40 wt.-% of particles having an average particles size of between 0.1 and 15 μm are entrapped. The membrane has a wall thickness of below 150 μm. Methods for preparing the membranes in various geometries, and use of the membranes for the adsorption, isolation, and/or purification of substances from a liquid are explored.
