US Classification:

264 49, 29458, 295271, 264 42, 264119, 264293, 423448

Abstract:

A process for preparing a gas permeable flexible graphite sheet is presented. The process includes providing graphite flakes; admixing the graphite flakes with a sacrificial additive to form a graphite mixture; compressing the graphite mixture into a sheet having sacrificial additive dispersed therethrough; and treating the sheet to at least partially remove the sacrificial additive to form a permeable flexible graphite sheet.

International Classification:

B32B 9/00

US Classification:

428408, 4234471, 165185

Abstract:

A method for preparing resin-impregnated graphite articles, including providing a sheet of compressed particles of exfoliated graphite having two major surfaces; impregnating the sheet with a first resin system to form a resin-impregnated sheet; surface treating the resin-impregnated sheet to form at least one structure on at least one of the major surfaces of the sheet to form a surface treated sheet; and treating the sheet with a second resin system.

International Classification:

B29C059/00

US Classification:

264069000, 264156000, 264293000

Abstract:

A method of forming impressions in a flexible graphite sheet is provided. More particularly, the inventive method involves contacting a flexible graphite sheet with an forming element capable of oscillating against the flexible graphite sheet, whereby the oscillations in the element are such that a plurality of impressions are formed in the flexible graphite sheet.

International Classification:

B05D001/12

US Classification:

427402000, 427180000

Abstract:

A method for improving the adhesion of a functional coating to an article formed of compressed particles of exfoliated graphite, which includes applying a primer coating to the article, where the primer coating has as its constituents at least some of the constituents of the functional coating and exhibits greater adhesion to the article than does the functional coating.

Abstract:

A composite article is provided for use as a heat spreader, a cooling element or as part of the heating system for a wide variety of items. The composite article can include at least one sheet of compressed particles of exfoliated graphite or graphiiized polymer. A protective coating may be aligned or adhered with a surface of the sheet. The article may also include at least one of a fiber reinforced polymer, a fiber weave or fiber mat or combinations thereof, aligned with at least one of the first surface of the sheet or a second surface of the sheet. The composite article can include a plurality of strips of compressed particles of exfoliated graphite, of graphiiized polymer or combinations thereof, which are woven together and or it can include cut outs, slits or other perforations to provide flexibility, stretchabi Kiv and breathability
