Abstract

Methods of making a composite material may include the steps of depositing a plurality of fullerenes on a first graphene sheet forming a bottom plate, placing a second graphene sheet forming a top plate on a top of the plurality of fullerenes, and fusing the plurality of fullerenes to the first graphene sheet forming the bottom plate and the second graphene sheet forming the top plate, wherein the plurality of fullerenes are converted to fullerene-derived carbon columns, and wherein the composite material comprises a tensile strength in an x-axis parallel to the plane of the graphene sheets of at least 20 GPa.

Claims (13)

1. A method of making a composite material comprising:

depositing a plurality of fullerenes on a first graphene sheet forming a bottom plate;

placing a second graphene sheet forming a top plate on a top of the plurality of fullerenes; and

fusing the plurality of fullerenes to the first graphene sheet forming the bottom plate and the second graphene sheet forming the top plate, wherein the plurality of fullerenes are converted to fullerene-derived carbon columns, and wherein the composite material comprises a tensile strength in an x-axis parallel to a plane of the graphene sheets of at least 20 GPa.

2. The method of claim 1 , wherein a laser is used to fuse the composite material.

3. The method of claim 2 , wherein the laser is configured to emit energy having a frequency from 450 nm to 700 nm.

4. The method of claim 1 , wherein the fullerene-derived carbon columns are positioned from about 0.5 nm to about 2 nm from each other.

5. The method of claim 4 , wherein the fullerene-derived carbon columns are positioned at least 0.5 nm from each other.

6. The method of claim 5 , wherein the fullerene-derived carbon columns are positioned from about 0.5 nm to 1 nm from each other.

7. The method of claim 6 , wherein the fullerene-derived carbon columns are positioned about 0.81 nm from each other.

8. The method of claim 1 , wherein the fullerene-derived carbon columns are positioned in a staggered pattern between the graphene sheets.

9. The method of claim 1 , wherein the fullerene-derived carbon columns are positioned in a uniform pattern between the graphene sheets.

10. The method of claim 1 , wherein the composite material comprises a maximum capacity of at least 1200 mAh/g.
