Abstract
The present disclosure relates to a membrane prepared from a blend comprising i) a polysulfone, polyether sulf one or polyarylethersulfone and ii) polyvinylpyrrolidone, characterized in that the membrane is coated with polydopamine and chon-droitin. Optionally the coating further comprises heparin. The disclosure further relates to a process for producing the coated membrane, a method of increasing the selectivity of a membrane, and to a filtration/diffusion device comprising the membrane which can be used, for example, in hemodialysis applications.
