Abstract

In one aspect, methods of making a carbon coating are described herein. In some implementations, a method of making a carbon coating comprises applying a first adhesive material to a substrate surface to provide an adhesive surface; rolling a carbon source over the adhesive surface to provide a carbon layer on the adhesive surface; and rolling an adhesive roller over the carbon layer to remove some but not all of the carbon of the carbon layer to provide the carbon coating.

First claim

That which is claimed is:

1 . An apparatus for forming a carbon coating comprising:
a handle; and a graphite rod or sphere attached to the handle,
wherein the graphite rod or sphere has a curved surface and is configured to roll when the handle is moved in a direction tangential to the curved surface of the graphite rod or sphere.

2 . The apparatus of claim 1 further comprising a moveable support structure attached to the handle.

3 . The apparatus of claim 2 , wherein the moveable support structure comprises a track mechanism.

4 . The apparatus of claim 2 further comprising a plurality of additional handles attached to a plurality of additional graphite rods or spheres, wherein the additional handles are attached to the moveable support structure.

5 . The apparatus of claim 1 further comprising a detector for determining a thickness of the carbon coating formed by the apparatus.

6 . The apparatus of claim 5 , wherein the detector comprises an acoustic wave detector.

7 . The apparatus of claim 5 , wherein the detector measures an optical absorption of the carbon coating formed by the apparatus.

8 . The apparatus of claim 5 , wherein the detector measures an electrical conductivity of the carbon coating formed by the apparatus.

9 . The apparatus of claim 1 further comprising:
a second handle; and
an adhesive roller attached to the second handle;

wherein the graphite rod or sphere and the adhesive roller are configured to roll over substantially the same area of a substrate when the first and second handles are moved in a direction tangential to the curved surface of the graphite rod or sphere or to a curved surface of the adhesive roller.

10 . The apparatus of claim 9 , wherein the apparatus is configured to roll the graphite rod or sphere over an area of the substrate before rolling the adhesive roller over the area.

11 . The apparatus of claim 1 , wherein the apparatus is operable to deposit the carbon coating over an area of more than 100 m 2 .

12 . A carbon-coated substrate comprising:
a substrate surface; a carbon coating disposed on the substrate surface; and an adhesive layer disposed between and immediately adjacent to the substrate surface and the carbon coating,
wherein the carbon coating has a thickness of up to 5 mm.

13 . The carbon-coated substrate of claim 12 , wherein the carbon coating comprises graphene.

14 . The carbon-coated substrate of claim 12 , wherein the substrate surface comprises a surface of a window or windshield, a surface of an electronic component, or an exterior surface of a vehicle.

15 . The carbon-coated substrate of claim 12 , wherein the substrate surface comprises an exterior surface of an aircraft.

16 . The carbon-coated substrate of claim 12 , wherein the carbon coating covers an area of more than 100 m 2 .
