First claim

The invention claimed is:

1. A method of forming a bulk product comprising the step of:
coating a particulate conductive phase material with a binder phase using a deposition coating process, and forming the coated conductive phase material into a bulk material;
wherein said particulate conductive phase material includes at least one of two dimensional (2D) materials, single layer materials, graphene, boron nitride nanotubes, aluminum nitride and molybdenum disulphide (MoS 2 ), carbides or nitrides including those of Ti and Si refractories, intermetallics and glasses;
wherein there is an intermediate layer coating between the conductive phase and the binder phase;
wherein the intermediate layer coating is a metal carbide and the binder phase is a transition metal;
wherein the binder phase coating is less than 100 microns thick; and
wherein said binder phase transition metal is copper, said intermediate layer coating is molybdenum carbide and said particulate conductive phase material is graphene.

2. The method as set forth in claim 1 , wherein the particulate conductive phase materials are in the shape of at least one of a powder, fibers, nanotubes, whiskers, spheres, and platelets.

3. The method as set forth in claim 1 , wherein the deposition process is one of molecular layer deposition, atomic layer deposition, and vapor phase, spray, paint, plating, solution dipping, electrostatic or electrophoretic deposition or other suspension deposition methods.

4. The method as set forth in claim 3 , wherein the binder phase material is selected such that it will facilitate preferential deformation, flow, or bonding with the conductive phase material into the bulk material.

5. The method as set forth in claim 4 , wherein the bulk material is at least one of sheet stock, tape, ribbons, wires, or other geometries including a final component.

6. The method as set forth in claim 1 , wherein the bulk material is to be utilized as part of a heat exchanger.

7. The method as set forth in claim 1 , wherein the bulk material is to be utilized as part of an electrical cable.

8. The method as set forth in claim 1 , wherein the bulk material is at least one of sheet stock, tape, ribbons, or wires.
