Summary
A new model is derived to calculate the solute diffusion coefficient through heterogeneous membranes consisting of a crosslinked, swollen phase and an impermeable, crystalline phase. The solute diffusion coefficient is shown to depend on various structural characteristics of the amorphous permeable phase and on the volume fraction of the impermeable phase.
