摘要：

This paper is a review of the kinetics of diffusion of small-molecule penetrants in semicrystalline polymers. The variations in diffusion impedance resulting from variations in morphology and segmental mobility in the amorphous component are highlighted. Deviations from Fickian diffusion appearing in many systems are discussed, as well as the effect of morphology, crystal orientation and chain orientation on the diffusivity.
