Abstract

A system for synthesizing carbon nanotubes (CNT) on a fiber material includes a surface treatment system adapted to modify the surface of the fiber material to receive a barrier coating upon which carbon nanotubes are to be grown, a barrier coating application system downstream of the surface treatment system adapted to apply the barrier coating to the treated fiber material surface, and a barrier coating curing system downstream of the barrier coating application system for partially curing the applied barrier coating to enhance reception of CNT growth catalyst nanoparticles.

Claims

1. A system for synthesizing carbon nanotubes (CNT) on a fiber material comprising:

a surface treatment system adapted to modify the surface of the fiber material to receive a barrier coating upon which carbon nanotubes are to be grown;

a barrier coating application system downstream of the surface treatment system adapted to apply the barrier coating to the treated fiber material surface; and

a barrier coating curing system downstream of the barrier coating application system for partially curing the applied barrier coating to enhance reception of CNT growth catalyst nanoparticles.

2. The system of claim 1, further comprising a catalyst application system for depositing CNT growth catalyst nanoparticles.

3. The system of claim 2, wherein said CNT growth catalyst nanoparticles comprises iron.

4. The system of claim 2, wherein the catalyst application system and barrier coating application system are configured for simultaneous deposition of catalyst nanoparticles and barrier coating.

5. The system of claim 2, wherein the catalyst application system is upstream of the barrier coating system.

6. The system of claim 2, wherein the catalyst application system is downstream of the barrier coating system.

7. The system of claim 2, further comprising a CNT growth system comprising a CNT growth chamber equipped with a carbon feedstock supply for chemical vapor deposition (CVD)- or plasma-enhanced CVD-growth of carbon nanotubes.

8. The system of claim 7 configured for the continuous synthesis of carbon nanotubes on the fiber material, wherein the fiber material is provided in spoolable lengths on a spool or mandrel from a payout system upstream of the surface treatment system and wherein the fiber material is re-wound downstream of the CNT growth system.
