| Popis: | Pore morphology of experimental micropore carbon materials was explored using non-destructive methods. The influence of the heat treatment on porosity of two micropore carbon materials was investigated using helium porosimetry (HP) and X-ray micro-computed tomography (µCT). Methodology of µCT image processing and separation of the total and the open porosity is presented. In both materials open pores were found over the whole height of the sample. The local pore thickness and tortuosity of the materials were calculated. The increase of the porosity after heat treatment is observed for both materials. |
