Table 3 Summary and comparison of three most common CNT synthesis methods
From: Carbon nanotubes: properties, synthesis, purification, and medical applications
Method | Arc discharge | Laser ablation | CVD |
|---|---|---|---|
Yield rate | >75% | >75% | >75% |
SWNT or MWNT | Both | Both | Both |
Advantage | Simple, inexpensive, high-quality nanotubes | Relatively high purity, room-temperature synthesis | Simple, low temperature, high purity, large-scale production, aligned growth possible |
Disadvantage | High temperature, purification required, tangled nanotubes | Method limited to the labscale, crude product purification required | Synthesized CNTs are usually MWNTs, defects |
