Description	This contribution demonstrates the application of AFM (atomic force microscopy) and plasma etching in visualisation of the lamellar structure. Moreover, we have developed modeling tools capable of mapping between the semi-crystalline morphology and transport of penetrants. In this contribution we reconstruct spatially 3D structures of spherulites consisting of lamellae, calculate effective diffusivity of the reconstructed semi-crystalline structure and compare the results to experimental data of diffusion in compact films, fibers and particles with semi-crystalline structure. Diffusion of penetrants in semi-crystalline polymer proceeds only in amorphous phase. Crystalline lamellae not only slow down the transport (by the tortuosity effect), but also constrain the swelling of amorphous phase and thus slow down the transport in amorphous polymer. In the result section we show why polyethylene materials with the same crystallinity often exhibit widely different diffusivities. Moreover, we critically disc This contribution demonstrates the application of AFM (atomic force microscopy) and plasma etching in visualisation of the lamellar structure.
