Abstract

A flexible sheet comprising a composite sheet, the composite sheet comprising a binder and an aggregate containing a plurality of carbon nanotubes that is disposed in the binder, wherein the aggregate is formed as a waveform structure travelling along a single direction in a plane of the composite sheet, is provided. The disclosed flexible sheets may be used as thermally conductive components, electrically conductive components, antistatic components, electromagnetic wave shields, and/or heating elements, in addition to other possible uses.

First claim

What is claimed is:

1. A flexible sheet comprising a composite sheet, the composite sheet comprising an elastic binder and a carbon nanotube sheet containing a plurality of carbon nanotubes that is disposed in the elastic binder, wherein the carbon nanotube sheet has as a waveform structure with a plurality of peaks and valleys, the waveform structure travelling along a single direction in a plane of the composite sheet to enable the flexible sheet to be stretched in the direction of the waveform structure.

2. The flexible sheet of claim 1 , further comprising a support sheet that supports the composite sheet.

3. The flexible sheet of claim 2 , wherein the support sheet is an elastic sheet.

4. The flexible sheet of claim 1 , wherein the binder comprises a silicone component.

5. The flexible sheet of claim 1 , wherein the carbon nanotubes are metallized carbon nanotubes.

6. The flexible sheet of claim 5 , wherein the metallized carbon nanotubes comprise a first metal layer of titanium on the carbon nanotubes.

7. The flexible sheet of claim 6 , wherein the metallized carbon nanotubes comprise a second metal layer on the first metal layer of titanium.

8. The flexible sheet of claim 1 , wherein the carbon nanotube sheet comprises a plurality of carbon nanotube bundles.

9. The flexible sheet of claim 8 , wherein a diameter of a bundle of the plurality of carbon nanotube bundles is between 3 μm and 150 μm.

10. A thermally conductive component comprising the flexible sheet of claim 1 .

11. An electrically conductive component comprising the flexible sheet of claim 1 .

12. An antistatic component comprising the flexible sheet of claim 1 .

13. An electromagnetic wave shield comprising the flexible sheet of claim 1 .

14. A heating element comprising the flexible sheet of claim 1 .
