A series of membranes having a selective and reversible oxygen-binding capacity were prepared by complexing picket-fence cobaltporphyrin (CoP) as an oxygen carrier with various polymer matrixes. The oxygen-absorption isotherm and oxygen permeation in and through the membranes were properly analyzed by dual-mode models to give the physical solubility coefficient of oxygen (k D), the physical diffusion coefficient of oxygen through the membrane (DD), and the apparent diffusion coefficient of oxygen for hopping between fixed carriers (DC). The oxygen-binding equilibrium constant (K) of CoP was independent of the polymer matrix species. The D C value was smaller than the DD value, but the D C/DD ratio still remained in the range of 1/5-1/50, indicating that CoP fixed in the membrane reversibly binds oxygen and facilitates oxygen transport.
