Abstract: A surface modified multilayered composite membrane for the separation of oxygen enriched air comprises (a) porous polysulphone layer; (b) sulphonated polysulphone layer; (c) polysiloxane grafted layer formed by grafting polysiloxanes onto (b), and (d) rubber layer formed by coating and crosslinking polysiloxanes. The sulphonating agent is SO3/triethylene phosphate complex, the solvent is cyclo hexane, and the polysiloxane is dihydroxypolydimethyl siloxane. And the crosslinking agent is pref. tris (dimethylamino) methylsilane, tris (cycloamino) methylsilane, etheylacetoxy triacetate silane or methylacetoxy triacetate silane.
