The thermal interface of claim 1 wherein the protective coating comprises a thermoplastic material.

The thermal interface of claim 2 wherein the thermoplastic comprises polyethylene, a polyester or a polyimide.

The thermal interface of claim 1 wherein the protective coating is effective to electrically isolate the coated major surface of the sheet.

The thermal interface of claim 1 which further comprises a layer of adhesive interposed between the protective coating and the sheet.

An electronic device comprising (a) an electronic component; and (b) a thermal interface comprising a sheet of compressed particles of exfoliated graphite having two major surfaces, one of the major surfaces being in contact with the electronic component and the other of the major surfaces coated with a protective coating sufficient to inhibit flaking of the particles of graphite. view more

A thermal management system comprising a heat source having an external surface and a thermal interface which comprises an anisotropic flexible graphite sheet formed by compressing exfoliated particles of natural graphite and having a planar area greater than the area of the external surface of the heat source, the flexible graphite sheet having first and second major planar surfaces and having axes of higher thermal conductivity parallel to said major planar surfaces, one of said major planar surfaces being in direct operative contact with the heat source. view more
