Abstract
A thin film composite membrane comprises a core layer and a sheath UV-crosslinked polymer layer. The thin film composite membrane is produced by the co-extrusion of two polymer solutions. The core layer and the sheath layer can be separately optimized. The sheath layer may be UV-crosslinked to provide stability and selectivity at the desired operating temperature of the composite membrane.
