Abstract

The method of the present disclosure is directed towards the formation of a three-dimensional carbon structure and includes the steps of adding a radical initiator to an amount of carbon starting material, forming a mixture, placing the mixture in a mold, maintaining the mixture and the mold at an elevated temperature for a period of time to form a thermally cross-linked molded mixture and removing the thermally cross-linked molded mixture from the mold. The disclosure also includes a three-dimensional carbon structure, with that structure including a thermally cross-linked carbon base material in a predetermined formation.

First claim

What is claimed is:

1. A carbon structure having an elastic modulus from about 16 MPa to about 84 MPa and a hardness from about 0.7 MPa to about 4.9 MPa.

2. The structure of claim 1 , wherein the carbon structure has a pore diameter of between about 125 nm and about 325 μm.

3. The structure of claim 1 , wherein the carbon structure has a porosity of about 20% to about 95%.

4. The structure of claim 1 , wherein the carbon structure has a dimension greater than about 1 mm.

5. The structure of claim 1 , wherein the carbon structure has a bulk electrical conductivity of about 2×10 −1 S cm −1 .

6. The structure of claim 1 , wherein the structure is formed of a carbon material selected from the group consisting of multiwalled carbon nanotubes, single walled carbon nanotubes and combinations thereof.

7. The carbon structure of claim 1 , wherein the carbon structure further comprises a radical initiator.

8. The carbon structure of claim 7 , wherein the radical initiator is selected from the group consisting of a peroxide, benzoyl peroxide, a compound with a peroxide functional group (ROOR′), methyl ethyl ketone peroxide, Di-tert-butyl peroxide, benzoyl peroxide, acetone peroxide, bisacylphosphine oxide (BAPO), aluminophosphate (MAPO), tert-Amylperoxy-2-ethyl (TAPO) or azobisisobutyronitrile (AIBN) and combinations thereof.

9. The carbon structure of claim 7 , wherein the ratio of carbon material to radical initiator is between 1:0.5 to 1:4.
