SILICONE-ADDED POLYAMIDE COMPOSITE NANOFILTRATION MEMBRANE AND METHOD FOR FABRICATING THE SAME |
摘要 |
PURPOSE: Provided are a silicone-added polyamide composite nanofiltration membrane with excellent separation efficiency and high flux, and a method for fabricating the same. CONSTITUTION: The method comprises the steps of preparing diamine aqueous solution; contacting the diamine aqueous solution onto a porous substrate of polyacrylonitrile (PAN) for several minutes and removing excessive solution; preparing iso-paraffins solution and contacting it onto the porous substrate, thereby forming an interfacial polymerization layer on the porous substrate; and drying the interfacial polymerization layer in a dry oven at 90°C for several hours.
