Let us summarize the implications of our findings. Firstly, within our model, the ideal perm-selectivity obtained from permeability of individual components agrees well with the actual perm-selectivity. Using ideal permselectivity as a performance metric for polymer materials is a common practice in the membrane separations community. However, not all systems follow this assumption. Given the very general nature of the model, we can hypothesize that to observe non-ideal effects one must include other elements into the model such as the kinetic effects.
