Here, a series of parallel RC circuits was employed instead of the single RC circuit to take account of the four diffusion pathways, demonstrating solute transfer betwwen matrix and carrier. It was then examined against the experimental data on oxygen transport through poly(dimethyl siloxane), poly(butyl methacrylate) and poly(methyl methacrylate) with a metallo-porphyrin carrier. The current model showed a better agreement than the single circuit model but the difference was minor.
