Fabrication of Polyethersulfone Membranes


Ultrafiltration membranes are commercially made through non-solvent induced phase separation (NIPS). In this method, a polymer solution is cast as a film and immersed in a non-solvent, which results in formation of a porous polymer with nanometer size pores. The obtained porous film can separate solid particles, proteins, and macromolecules from water.
