TLDR
In this article, a model describing the influence of temperature on the permeability/selectivity tradeoff of polymeric membranes has been developed from fundamental theoretical considerations, and the model was used to predict the influence on upper bound behavior for several gas pairs including O 2 /N 2, H 2 /H 2, CO 2 /CH 4, CO 2/N 2, H 2 2 /CO 2, and CO 2 1/H 2. The predicted upper bound shifts vertically with temperature and the direction and magnitude of the shift depend on the sizes and condensabilities of theAbout:

The upper bound revisited
TL;DR: The empirical upper bound relationship for membrane separation of gases initially published in 1991 has been reviewed with the myriad of data now presently available as mentioned in this paper, which indicates a different solubility selectivity relationship for perfluorinated polymers compared to hydrocarbon/aromatic polymers.

The solution-diffusion model: a review
TL;DR: In this paper, the authors derived the phenomenological equations for transport in these processes using the solution-diffusion model and starting from the fundamental statement that flux is proportional to a gradient in chemical potential.
