Cover Story: Semicrystalline polymers are multiphasic materials nowadays used in several applications, spanning from gas barriers such as packaging and compressed gas storage to membrane separation processes, due to the good combination of mechanical and gas transport properties. This study is focused on the modelling of the gas transport properties in semicrystalline polymers through a tortuosity analysis based on the finite-volumes method. The results obtained were compared with existing analytical models, which were extended to better describe such a system, up to high crystallinity, to include the effect of the shape, aspect ratio and orientation of the crystalline domains.
