Abstract: The authors set out to prepare cellular vitreous carbon (CVC) foams with varying thermal and physical properties. This was accomplished by using tannin-based resin modified by different isocyanates in varying amounts. Three different experimental procedures were used to prepare foams with different physical and thermal properties. Physical properties of the foams studied include density, as well as pore volume, pore size and cell diameter. The transient plane source (TPS) technique was used to measure the thermal conductivity of the prepared foams. The foams modified using isocyanate had thermal conductivities below 0.1 W/mK.
