Abstract

HIGHLY PERMEABLE DOUBLE-SKINNED FORWARD OSMOSIS MEMBRANE FOR ANTI-FOULING IN THE EMULSIFIED OIL-WATER SEPARATION PROCESS 5 A double-skinned membrane that includes a polymeric support having a thickness of 20 to 500 µm, a first surface and a second surface opposed to each other; a polymeric thin film layer having a thickness of 1 to 1000 nm and covering the first surface; and a sulfonated pentablock copolymer layer having a thickness of 1 to 1000 nm and covering the second 10 surface. Also disclosed is a method of preparing the above-described double-skinned membrane.
