Summary:A carbon foam material with improved graphitizability is formed by including a graphitization promoting additive into the carbon foam. The graphitization promoting additive greatly improves the graphitic structure of the carbon foam resulting in a carbon foam with much greater thermal and electrical conductivities. This inventive foam may be created by introducing the graphitization promoting additive during the catalysis of a phenol-aldehyde mixture to a form phenolic resin or during the conversion of the phenolic resin to a phenolic foam. Alternatively, the graphitization promoting additive can be fixed onto a preformed carbon foam.
