X-ray tomography reconstruction of porous polyolefine particles
Original language description
X-ray micro-tomography is a powerful technique providing us with the information about structure of porous or multi-phase samples. X-ray tomography allows visualizing the combined distribution of material density and nucleon number. The currently achievable resolution with the laboratory source of X-rays is hundreds of nanometers. Tomography images can serve also as the input for the computation of material properties, e.g., of effective diffusivity of species in porous particles. Here we report our experience with Micro-CT attachment for SEM from SkyScan company. Several classes of polymer samples were visualized: (i) porous polyethylene and polypropylene particles, (ii) compact, i.e., non-porous materials, and (iii) polymeric foams. We critically investigate, how ambiguous is the whole processes starting with X-ray tomography and resulting with binarized phase function and calculated transport properties of the sample. More specifically, we are concerned with the sensitivity to perso
