    Abstract: 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.

    Abstract: A glassy carbon coated carbon foam material is formed by coating carbon foam with a glassy carbon layer. Carbon foam may be produced by carbonizing a phenolic or polyurethane foam at high temperatures in an inert atmosphere. The carbon foam is then machined to a desired shape and treated with a fine carbon or graphite powder to the surface. Subsequently a resin is applied to the surface of the carbon foam, and the coated carbon foam block is fired to carbonize the resin coating into a glassy carbon coating. The firing and coating are repeated until the desired coating thickness and surface properties are achieved.

    Abstract: 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.

    Abstract translation: 通过在碳泡沫中包含含氧化促进金属的添加剂并随后在反应性气氛中对泡沫进行热处理，形成具有改善的石墨化性的活性炭泡沫材料。 含氧化促进金属的添加剂大大改善了碳泡沫的分枝孔体系的发展，导致具有更大表面积的碳泡沫。 本发明的泡沫体可以通过在酚醛树脂的聚合过程中通过氧化催化剂引入氧化促进金属或作为无机化学活化剂引入所形成的酚醛树脂中来产生。 然后将泡沫在反应性气氛中加热以产生表面积为约200m 2 / g至约3000m 2 / g的活化泡沫。
