Abstract

A three-dimensional porous composite structure comprises a porous structure and at least one carbon nanotube structure. The porous structure has a plurality of metal ligaments and a plurality of pores. The at least one carbon nanotube structure is embedded in the porous structure and comprising a plurality of carbon nanotubes joined end to end by van der Waals attractive force, wherein the plurality of carbon nanotubes are arranged along a same direction.

First claim

What is claimed is:

1 . A three-dimensional porous composite structure, comprising:
a porous structure comprising a plurality of metal ligaments and a plurality of pores; at least one carbon nanotube structure embedded in the porous structure and comprising a plurality of carbon nanotubes joined end to end by van der Waals attractive force, wherein the plurality of carbon nanotubes are arranged along a same direction.

2 . The three-dimensional porous composite structure of claim 1 , wherein each of the plurality of pores is defined by adjacent metal ligaments.

3 . The three-dimensional porous composite structure of claim 2 , wherein size of each of the plurality of pores is less than or equal to 100 μm.

4 . The three-dimensional porous composite structure of claim 1 , wherein the plurality of metal ligaments are composed of inert metal materials.

5 . The three-dimensional porous composite structure of claim 1 , wherein one part of the carbon nanotube structure is embedded in the plurality of metal ligaments, and another part of the carbon nanotube structure is located in the plurality of pores.

6 . The three-dimensional porous composite structure of claim 1 , wherein the at least one carbon nanotube structure comprises a plurality of carbon nanotube structures spaced from each other.

7 . The three-dimensional porous composite structure of claim 6 , wherein an angle between carbon nanotubes in adjacent spaced carbon nanotube structures is in a range from 0° to 90°.

8 . The three-dimensional porous composite structure of claim 7 , wherein the adjacent spaced carbon nanotube structure are parallel with each other.

9 . The three-dimensional porous composite structure of claim 1 , wherein the carbon nanotube structure comprises at least one carbon nanotube film, the at least one carbon nanotube film is a drawn carbon nanotube film comprising a plurality of successively oriented carbon nanotube segments joined end-to-end by van der Waals force therebetween.

10 . The three-dimensional porous composite structure of claim 9 , wherein the at least one carbon nanotube film comprises a plurality of carbon nanotube films coplanar or stacked.

11 . The three-dimensional porous composite structure of claim 10 , wherein an angle between carbon nanotubes in adjacent stacked carbon nanotube films is in a range from 0° to 90°.
