CLAIMS :
1. A method for producing a material with nanomaterials attached, comprising:

applying a nanoink on a substrate to form a first layer, the nanoink comprising nanomaterials and a first solvent;
removing the solvent from the nanoink thus obtaining a nanolayer consisting of nanomaterials adhered to the substrate
applying a material layer on the nanolayer to form a second layer, the material layer comprising a material and a second solvent;
removing at least some of the solvent from the second layer; and
peeling the second layer from the substrate whereby the nanolayer adheres to the second layer.

2. The method of claim 1 wherein the peeled second layer is transparent and flexible.

3. The method of claim 1 or claim 2 further comprising applying the material layer on the nanolayer at room temperature.

4. The method of any one of claims 1 to 3 further comprising selecting the first solvent in the nanoink from a group comprising an organic solvent and water plus a surfactant.

5. The method of any one of claims 1 to 4 wherein the substrate is selected from a group comprising organic and inorganic materials .

6. The method of claim 5 further comprising treating the
substrate with a monolayer of silane prior to the applying of the nanoink.

7. The method of any one of claims 1 to 6 wherein a surface of the peeled second layer is one of square, rectangular, circular, triangular, rhombus, polygonal, linear, and a point in shape.

8. The method of any one of claims 1 to 7 wherein the material is one of a polymer and a small molecule material.

9. The method of any one of claims 1 to 8 further comprising applying an additional material layer to the second layer for enhancing physical properties of the second layer.

10. The method of any one of claims 1 to 9 wherein the applying of the material layer comprises drop casting the material layer onto the nanolayer.

11. The method of any one of claims 1 to 10 wherein the peeling of the second layer from the substrate comprises one of pulling and shearing the second layer from the substrate.

12. The method of any one of claims 1 to 11 wherein the removing of the at least some solvent comprises baking the second layer.

13. The method of claim 12 further comprising peeling the second layer from the substrate whereby the nanolayer adheres to the second layer.

14. A product having a selective electrically conducting surface comprising:

a transparent material with at least one planar surface; and

a layer of nanomaterials embedded in one planar surface of the material.

15. The product of claim 14 wherein the planar surface of the material is square, rectangular, circular, triangular, rhombus, polygonal, linear, or a point in shape.

16. The product of claim 14 or claim 15 wherein a second
transparent material is adhered to the transparent material.

17. The product of any one of claims 14 to 16 wherein the
nanomaterials are electrically conductive or semi-conductive.

18. The product of any one of claims 14 to 17 wherein the
nanomaterials are uniformly dispersed and highly interconnected when embedded in the planar surface of the material.

19. The product of any one of claims 14 to 18 wherein the planar surface with nanomaterials has a surface conductance greater than 0.001 siemens/square .

20. The product of any one of claims 14 to 19 wherein the
transparent material with nanomaterials embedded in the at least one planar surface has an optical transmittance greater than 80%.

21. The product of any one of claims 14 to 20, wherein the depth of nanomaterials embedded in one planar surface of the material is less than 200nm.
