摘要：
A membrane for the purification of blood, or a dialysis membrane, in hollow-fiber membrane or flat membrane geometry, made of a composite assembled from at least a base membrane based on at least one polysulfone or a polyphenylsulfone with at least one pore-forming hydrophilic additive and at least one functional layer arranged on the base membrane, whereby the functional layer is formed from at least one polymeric polycationic bonding agent and at least one polymeric polyanion, whereby the base membrane is made of a material which is selected from: a polysulfone [PSU], a sulfonated polysulfone [SPSU], a polyethersulfone [PES], a sulfonated polyethersulfone [SPES], a polyphenylsulfone [PPSU], a sulfonated polyphenylsulfone [SPPSU]； and mixtures of these.
