Pore volume, pore diameter, pore volume distribution and pore throat diameters of nanofiber mats were measured using mercury intrusion porosimetry, liquid extrusion porosimetry and capillary flow porometry. Analysis of results showed that mercury intrusion distorts the structure due to application of high pressure. Liquid extrusion does not require high pressures, gives good resolution and measures pore structure relevant for application. Capillary flow porometry uses low pressures, measures pore throat diameter, but does not measure pore volume.
