Assessment of thickness-dependent gas permeability of polymer membranes

Abstract

Morphological changes with thickness, and the subsequent effect on the membrane permeability have been discussed qualitatively. It is concluded that some morphological elements favor transport and some hinder. Flux models based on interface reaction have been successfully applied to describe quantitatively the thickness-dependence of the membrane-permeability and the model parameters (diffusion transport coefficient, surface reaction constants) evaluated.
