  • Perfluorocarbon-free membranes for membrane distillation
    Patent number: 11648514
    Abstract: A perfluorocarbon-free membrane composed of a non-perfluorocarbon material having a first side and a second side opposite of the first side. The perfluorocarbon-free membrane also includes a plurality of pores, each having an inlet and outlet and each passing through the non-perfluorocarbon material so that each pore provides fluidic communication between the first and second sides of the non-perfluorocarbon material. A portion of the non-perfluorocarbon material extends over the inlet and outlet of each the plurality of pores so that a cross-sectional area of the inlets and outlets in a direction of the extension of the non-perfluorocarbon material is smaller than a cross-sectional area of the respective pore in the direction of the extension of the non-perfluorocarbon material. The perfluorocarbon-free membrane does not include a hydrophobic perfluorocarbon coating.
