The objective of this work is to compare three techniques for characterizing the morphology of porous biobased carbon foam, namely mercury intrusion porosimetry, scanning electron microscopy and X-ray microtomography. The first two techniques are commonly used in this field, while X-ray microtomography is a more recent characterization technique derived from medical tomography. Our study demonstrates the added value of the latter technique, especially concerning the evaluation of porosity, cell size distributions and cell connectivity. In this study we have shown that the material have a total porosity of around 90% with a cell size of less than 100 microns.
