  • Process for the production of hyperfiltration membranes
    Patent number: 4873033
    Abstract: The invention relates to a hyperfiltration membrane containing a supporting layer and a separation layer. The membrane is characterized in that the separation layer consists of a crosslinked monomolecular film of molecules, the molecules of the separation layer in the uncrosslinked state being surfactants or surfactant-like lipoids containing at least one hydrophobic chain and at least one hydrophilic group, the hydrophobic chains of these molecules being oriented mainly perpendicularly to the plane of the membrane and parallel to the diffusion direction after crosslinking and the molecules of the separation layer being crosslinked with one another through functional groups in at least one of their hydrophobic chains and/or through functional groups in at least one of their hydrophilic groups.
    Type: Grant
    Filed: June 22, 1988
    Date of Patent: October 10, 1989
    Assignee: Klaus Heckmann
    Inventors: Klaus Heckmann, Georg Manecke, Beate Pfannenmuller, Klaus Ring, Helmut Ringsdorf
