LIQUID-REPELLING PERMEABLE MEMBRANE

摘要

The invention relates to a permeable membrane (1) for repelling one or more liquids (2). The membrane (1) includes at least one face (4) which is based on a material that repels said liquids (2) and is provided with a plurality of protrusions (5.1 to 5.n). The membrane (1) is provided with a plurality of through-holes (7.1 to 7.n) that emerge on said face (4). The protrusions (5.1 to 5.n) are uniformly distributed in a defined manner in at least one region (10) on said face (4). The protrusions (5.1 to 5.n) also include at least one irregular surface (4) provided with microprotrusions (17).
