The difference between the single-walled carbon nanotube and multi-walled carbon nano-tube are as follows-
| Single-walled carbon nano-tube | Multi-walled carbon nano-tube |
|---|---|
| SWNT is made up by rolling a graphene sheet into a seamless cylinder. | MWNT is made up by the concentration of carbon nanotubes. |
| SWNT require optimization of experimental parameters for synthesis. | MWNT are synthesized easily. The may be found in the emission of LPG or propane based fuels. |
| The internal diameter is comparatively smaller(approximately 5-10nm). | They have well-ordered graphite structures. |
| SWNT bare used in electronics, water filtration, hydrogen storage, oil spill removal etc. | MWNT have comparatively fewer applications. |
