The carbon nanotubes are widely used in many applications of nanotechnology. These carbon nanotubes may have either single wall or multiple walls, as created by the scientists. Earlier single walled carbon nanotubes were more popular in this field, due to the simplicity of their properties. Now, sheets of multi walled carbon nanotubes are also produced by the research scholars working with nanotechnology. These nanotubes have wider ranges in all their physical properties, based on their structural differences.
 

These carbon nanotubes have immense strength and can be elastically stretched to a great extent, which is even more than steel. The reason of this strength is the special sp2 bonds existing between the carbon atoms, which is more stable than the atomic bonds seen in diamond.
 
The multi walled carbon nanotubes have superb electrical conductivity, owing to the strong atomic bonds and least numbers of collisions among the moving carbon electrons. Thus, the scientists now prefer to buy multi walled carbon nanotubes online, as they can use these nanotubes in all types of semiconductors.  These nanotubes can pass electrical current of speed up to 10 GHz.

The thermal conductivity of the multi walled carbon nanotubes is very high, as they can bear very high temperatures. The thermal power of these carbon nanotubes is 15 times greater than that of copper. However, the range of their thermal conductivity depends on the atmospheric temperature and the heat provided to these tubes.
 
These nanotubes are pure polymers of carbon, for which they can be used in many applications, due to the useful chemical properties of this element. This feature encourages people to opt for multi walled carbon nanotubes online purchase so rapidly.
 

The multi walled carbon nanotubes are used in all the common batteries, solar cells, transistors of electronic appliances, flat display panels of televisions and also in other applications of nano-electronics. It is found that the anodes of the lithium ion batteries are made of multi walled carbon nanotubes are more functional than that made of simple graphite. Moreover, these anodes made of carbon nanotubes can store much more energy within the batteries.

Thus, so many applications inspire more purchases of multi walled carbon nanotubes online for the scientists who work in this field of nanotechnology. They only need to select the exact sizes of carbon nanotubes and place their orders on the websites of the selected suppliers.
