A membrane with an oxygen-binding capability and nanometer thickness was prepared by complexing cobalt-phthalocyanine as an oxygen carrier with the copolymer of vinylimidazole and octyl methacrylate. The complex showed reversible oxygen-binding in the solution state at low temperature. The permeability coefficient of oxygen (PO2) through this membrane was much higher than that of nitrogen (PN2)(PO2 / PN2 > 20) and increased at lower upstream oxygen pressure. The facilitation of oxygen transport was augmented by increasing the concentration of the oxygen carrier, cobalt-phthalocyanine fixed in the membrane.
