US Patent No: 7615204

Direct synthesis of long single-walled carbon nanotube strands

---

Abstract

---

Long, macroscopic nanotube strands or cables, up to several tens of centimeters in length, of aligned single-walled nanotubes are synthesized by the catalytic pyrolysis of n-hexane using an enhanced vertical floating catalyst CVD technique. The long strands of nanotubes assemble continuously from ropes or arrays of nanotubes, which are intrinsically long. These directly synthesized long nanotube strands or cables can be easily manipulated using macroscopic tools.
