Gas separation membrane comprising a porous support onto which is deposited a nanoporous single-layer graphene film with a CO2-philic polymer film having a thickness of 5-100 nm coated on top of graphene nanopores, acting as a CO2-selective film, wherein the CO2- philic polymer is swollen with another low molecular-weight CO2-philic polymer.
