NANOFILTRATION MEMBRANE WITH A LAYER OF POLYMER AND OXIDE PARTICLES

摘要

The invention relates to a nanofiltration membrane with a porous support membrane, the surface of the support membrane being coated with rubber-like polymer particles, produced by emulsion polymerisation and having an average particle diameter of less than 70 nm, preferably between 30 and 60 nm, particularly preferably between 40 and 50 nm and having at least one nanoparticulate oxide from the series Fe2O3, Fe3O4, Fe(OOH), TauiOmicron2 and SiO2. The rubber-like polymer particles are obtained from monomers which contain at least one conjugated diene as a functional group.
