Abstract: Composite carbon foams were prepared by mixing tannin-based resin with various graphite powders in an effort to improve the thermal conductivity relative to pristine carbon foams in order to use them as hosts for phase-change materials. It was found that using graphite powder with smaller particle sizes resulted in foams with a higher bulk density than those prepared with an equal amount of larger graphite particles, this increased density resulted in a higher thermal conductivity and improved mechanical properties over the other composite foams investigated. These inexpensive carbon foams have potential for future use as a host for phase change materials.
