Diffusion in semi-crystalline polymers

Abstract This contribution demonstrates the developed modeling tools capable of mapping between the semi-crystalline polymer morphology and transport of penetrants. Thus an understanding is brought to the area dominated by empirical knowledge that fails to describe even simple sets of experimentally measured transport characteristics. In this contribution we reconstruct spatially 3D structures of spherulites consisting of lamellae and calculate effective diffusivity of the reconstructed semi-crystalline structures.
