Specific and facilitated transport of molecular oxygen through a polymer membrane containing [α-mono(o-methacrylamidophenyl)-α,α,α-tris (o-pivalamidophenyl) porphinato]cobalt (CoMPP) complex as a fixed oxygen carrier is analyzed by a modified dual-mode transport theory, and the effect of the polymer matrix on the oxygen diffusion via the fixed carrier is discussed. Oxygen diffusion coefficients for the diffusion from the polymer matrix to the fixed carrier (DDC) and for the diffusion from the fixed carrier to the polymer matrix (DCD) increase with physical diffusivity through the polymer matrix. In contrast, the oxygen diffusion coefficient for hopping between the fixed carriers (DCC) is independent of the polymer matrix species.
