Silicone-coated organic solvent resistant polyamide composite nanofiltration membrane, and method for preparing the same

摘要

The present invention relates to a silicone-coated organic solvent resistant polyamide composite nanofiltration membrane and a method for preparing the same. More particularly, the present invention relates to a nanofiltration composite membrane that is not only rejection rate superior but also organic solvent stable and flux excellent, prepared by coating with silicone during the process of interfacial polymerization of polyamide on the surface of porous support; and a method for producing it.
