Single Walled Carbon Nanotubes
Interesting Facts About Single Walled Carbon Nanotubes
Part of the carbon nanotube family, single walled nanotubes (SWNTs) are robust nanostructures that are known for their extraordinary electrical, mechanical and optical properties. These are regarded to be an integral aspect of the CNTs, as significant changes are seen in the tubes with addition to multiple outer layers. Based on this structural difference, carbon nanotubes are categorized into:
- Single Walled Nanotubes (SWNTs)
- Double Walled Nanotubes (DWNTs)
- Multi-Walled Nanotubes (MWNTs)
Just as the name suggests, in single-walled nanotubes, the structure consists of a single cylindrical layer made up of graphene atoms. These atoms are placed in honey-comb lattice, forming a zigzag pattern that gives its strength and rigidity. Their chemical bonding involves sp2 hybridization, making it over 100 times stronger than diamond.
What is The Importance of Single Walled Carbon Nanotubes?
There are certain impeccable properties exhibited by SWNTs and this something that makes them one of their own kinds. Some of these exceptional abilities are mentioned below:

- The single walled carbon nanotubes hold the potential to miniaturize electronics. Now, the core element of such systems is electrical wires and these tubes with a diameter less than 1nm can act as amazing conductors.
- The effectiveness of SWNTs led to the development of first ever intermolecular field-effect transistors (FET) and these transistors utilized nanotubes as their logic date. The logic gate needs both n-FET and p-FET. As, SWNTs formed p-FET when they were exposed to oxygen, it was possible to keep one side of the transistor in presence of oxygen and the other side away from it.
- In span of ten years, the price of these tubes has reduced to almost $7 per gram, encouraging researchers to buy single walled carbon nanotubes. This led to the widespread usage of the nanotubes, along with improvements seen in their method of synthesis. Researchers believe that such a trend can leave a huge impact on the electronics industry by 2020.
How to Buy Single Walled Carbon Nanotubes?
Now that you are aware of some of the finest properties of this nanotube, you would definitely want to make the most of them, by experimenting their future prospects. For this, you have to buy single walled carbon nanotubes that are able to deliver the results that you are in search of. Fortunately, there are many online stores out there that provide a wide range of carbon nanotubes and that too at affordable prices. However, when you are shopping for them online do make sure that you consider:
- Dimensions: The dimensions of single walled carbon nanotubes are of utmost importance. Understand the requirements that you have and then decide the length that would be ideal for the same.
- Type: There are two common variants of these tubes available in the market and they are: SWNTs powder and functionalized SWNTs, again this is influenced by the properties that you want to explore or the applications that you are planning to implement.
- Price: Compare the price of SWNTs from one store to another and then opt for those who you think is able to provide the best quality and that too at value for money prices.
