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. A method of making a carbon coating comprising:
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 a carbon coating.

2. The method of claim 1 , wherein the carbon coating has a lower average thickness than the carbon layer.

3. The method of claim 1 , wherein the adhesive roller comprises a second adhesive material differing from the first adhesive material.

4. The method of claim 3 , wherein the second adhesive material is less adhesive to carbon than the first adhesive material is.

5. The method of claim 1 , wherein the carbon source comprises graphite.

6. The method of claim 1 , wherein the carbon layer comprises graphene.

7. The method of claim 1 , wherein the carbon layer is substantially continuous across the adhesive surface.

8. The method of claim 1 , wherein the carbon layer has an average thickness of up to about 1000 μm.

9. The method of claim 1 , wherein the carbon coating comprises graphene.

10. The method of claim 1 , wherein the carbon coating is substantially continuous across the adhesive surface.

11. The method of claim 1 , wherein the carbon coating has an average thickness of up to about 100 nm.

12. The method of claim 1 , wherein the carbon coating comprises one or more graphene sheets having a total of 1 to 10 atomic layers.

13. A method of making a carbon coating comprising:
applying a first adhesive material to a substrate surface to provide an adhesive surface and
rolling a carbon source over the adhesive surface to provide a carbon layer on the adhesive surface,

wherein the carbon source comprises a graphite rod.

14. A method of making a carbon coating comprising:
applying a first adhesive material to a substrate surface to provide an adhesive surface; and
rolling a carbon source over the adhesive surface to provide a carbon layer on the adhesive surface,

wherein the carbon source is an apparatus comprising a handle and a graphite rod or sphere attached to the handle, wherein the graphite rod or sphere is configured to roll when the handle is moved in a direction tangential to a curved surface of the graphite rod or sphere.
