Abstract
An asymmetric or double-sided porous material, which comprises at least one porous layer of a polymer on a porous support or carrier, where the polymer is formed from a self-assembled microstructured liquid. A method of producing the same comprising positioning the support or carrier against or adjacent an inert surface, providing an excess of polymerisable liquid to completely wet the carrier and form a film through capillary action between the carrier and the inert surface and penetrating the carrier, then polymerising the liquid.
