Mosaic hollow fiber membranes with polyelectrolytes
Within this research project, we developed a single-step fabrication process of novel mosaic hollow fiber membranes. We fabricated the fibers with a scalable spinning process using polyelectrolytes (PEL). The PELs form a mosaic structure of differently charged areas on the inside of the membrane, that enable ion transport during filtration operation. In addition, the layer is dense so that the membrane retains low-molecular organic compounds.
