The carbon foams imaged using X-ray micro-CT (v|tome|x s, GE Sensing & Inspection Technologies, phoenix|x-ray, Wunstorf, Germany). The samples were placed on the polymer stand and scanned at 80 kV and current of 130 μA. For each carbon foam 1000 scans were obtained at a total scan time of 15 min. The established scan parameters allowed to register an image with optimal contrast and a resolution of 10 μm. The acquisition of micro-CT projections was carried out in a 8-bit grey scale in order to identify changes in the microstructure of the analysed samples. Image acquisition was carried out using the micro-CT system (GE Sensing & Inspection Technologies, Wunstorf, Germany) providing a sequence of 2D images. The reconstruction was conducted and visualizes using VGStudio MAX 2.1 software (Volume Graphics, GmbH., Heidelberg, Germany)
