摘要： A carbon foam material with an improved oxidation resistance is created by blending formaldehyde with phenol to form a reactive mixture, polymerizing the reactive mixture with a non-oxidation promoting basic catalyst to form a resin article, foaming the resin article to create phenolic foam, and carbonizing the phenolic foam to create the carbon foam with an increased oxidation resistance. Specifically, the oxidation resistant carbon foam has a sodium content of approximately 0%. This inventive foam may also contain one or more oxidization inhibitors to impede the oxidation of the carbon foam when the foam is exposed to an oxidizing environment.

摘要： A sugar/additive blend useful as a binder or impregnant for carbon products. Simple sugars as well as sucrose are combined either in solution or in solid form with reactive additives such as ammonium hydrogen phosphate, ammonium chloride and para-toluene sulfuric acid. The sugar/additive blends form more and denser carbon residue than sugar alone when subjected to pyrolysis.

摘要： 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.

摘要： A method of forming a carbon fiber reinforced carbon composite articles includes the steps of: (a) selecting carbon fiber bundles that have a sizing material that is soluble in a selected dispersing fluid; (b) mixing the selected carbon bundles and other blend components in a dispersing fluid so as to debundle the carbon fibers and to produce a slurry of blend components in which the individual carbon fibers are substantially randomly oriented and uniformly distributed throughout; and (c) removing the dispersing fluid either prior to or during the process of forming of the solids of the slurry into a carbon fiber reinforced carbon composite article having individual carbon fibers substantially randomly oriented and uniformly distributed throughout.

摘要： An activated carbon foam material with improved graphitizability is formed by including an oxidation promoting metal-containing additive into the carbon foam and subsequently heat treating the foam in a reactive atmosphere. The oxidation promoting metal-containing additive greatly improves the development of the carbon foam's ramified pore system resulting in a carbon foam with a much greater surface area. This inventive foam may be created by introducing the oxidation promoting metal by way of an oxidation catalyst during the polymerization of the phenolic resin or as a inorganic chemical activating agent to the formed phenolic resin. The foam is then heated in a reactive atmosphere to produce an activated foam with a surface area of from about 200 m2/g to about 3000 m2/g.
