Abstract: The invention presented relates to a process for providing increased electrical and/or thermal conductivity to a material, and to the materials prepared by the process. More particularly, the invention relates to a process involving applying particles of expanded graphite to a substrate or material in order to increase its conductivity. The particles of expanded graphite can be applied to the substrate or material through coating of the substrate with a composition comprising the expanded graphite particles, or by incorporating particles of expanded graphite into the substrate or material itself.

Abstract: A release lined pressure sensitive adhesive flexible graphite sheet article is provided having low thermal resistance properties comparable to the flexible graphite material itself when compared to prior art PSA sheet products and wherein the release liner is easily removed with the sheet is to be used without any significant delamination of the flexible graphite. The flexible graphite sheet comprises a flexible graphite substrate, an adhesive primer coating thereon, a pressure sensitive adhesive coating on the adhesive primer coating and a release liner applied to the pressure sensitive adhesive coating. Double sided pressure sensitive adhesive flexible graphite sheets can also be made using the method of the invention.

Abstract: Intercalated graphite flake which has enhanced exfoliation volume characteristics at relatively low exfoliation temperatures e.g. 600.degree. C. is made by heating a blend of intercalated particles and an organic reducing agent in the temperature range of 25.degree. to 110.degree. C.
Abstract: Flexible graphite sheet is made by compressing a mixture of fine particle of intercalated, exfoliated, expanded natural graphite with fine particles of intercalated, unexpanded, expandable particles of natural graphite, the unexpanded particles being more finely sized than the expanded particles. The resulting sheet of flexible graphite exhibits improved fire retardant and sealability properties.
Abstract: Flexible graphite sheet having embedded ceramic fibers extending from its opposite planar surfaces into the sheet to provide permeability of the sheet to gases so that it is useful as an electrode in electrochemical fuel cells.
