Table 1 Comparison between SWNT and MWNT[4]
From: Carbon nanotubes: properties, synthesis, purification, and medical applications
SWNT | MWNT |
|---|---|
Single layer of graphene | Multiple layers of graphene |
Catalyst is required for synthesis | Can be produced without catalyst |
Bulk synthesis is difficult as it requires proper control over growth and atmospheric condition | Bulk synthesis is easy |
Purity is poor | Purity is high |
A chance of defect is more during functionalization | A chance of defect is less but once occurred it is difficult to improve |
Less accumulation in the body | More accumulation in the body |
Characterization and evaluation is easy | It has very complex structure |
It can be easily twisted and is more pliable | It cannot be easily twisted |
