Top 10 Uses Of Carbon Nanotubes:

Top 10 uses of Carbon Nanotubes: It was first discovered 25 years ago by lijima when he was studying the synthesis of fullerenes by using electric arc discharge technique. And it was a break through discovery that stunt the world quite remarkably.

Carbon nanotubes that Iijima observed were so called multi-walled carbon nanotubes (MWNTs) as shown in Fig. 1a, nested as Russian dolls, containing at least two graphitic layers, and generally have inner diameters of around 4 nm. Two years later, Iijima and Ichihashi of NEC [2] and Bethune and colleagues of the IBM Almaden Research Center in California [3] synthesized single-walled carbon nanotubes (SWNTs), After then the carbon nanotubes became the most highlighted material to all the researchers and the whole world.

Carbon nanotubes (aka CNTs) are made from (grapheme) sheets consisting of a single atomic layer of carbon atoms in a honeycomb framework that can be rolled into a tube measuring about a nanometer, or one billionth of a meter, in diameter, Almost every industry uses its application to benefit the most from it but the most popular and top 10 uses of carbon nanotubes that benefit from most of it are listed below.

Top 10 Uses of Carbon Nanotubes


  1. Electrical cables wires and circuits

Researchers have found that nanotubes fiber with the composite of copper have the capacity to performed 100 times more than pure copper and gold, and also have the exceeding capacity to outperform in terms of data transmission and power.

Large structures of carbon nanotubes can be used for thermal management of electronic circuits. An approximately 1 mm–thick carbon nanotube layer was used as a special material to fabricate coolers, this material has very low density, ~20 times lower weight than a similar copper structure, while the cooling properties are similar for the two materials.

  1. Battery

Today world lithium ion batteries use by many industries for variety of reason but specific to most popular uses are (Mobile, laptops, tablets and vehicles).

Researchers from the past 2 decades became very busy to fix the issue of how to increase the time of battery life which is now the most affected areas of today’s world especially for electronic devices, and now presumably  the issue is about to be resolved by using carbon nanotube in lithium ion batteries,  they are being experimented as a new electrode material, particularly the anode for lithium ion batteries, This is due to the fact that the anode requires a relatively high reversible capacity at a potential close to metallic lithium, and a moderate irreversible capacity, observed thus far only by graphite-based composites, such as CNTs, They have shown to greatly improve capacity and cyclability of lithium-ion batteries, as well as the capability to be very effective buffering components, alleviating the degradation of the batteries that is typically due to repeated charging and discharging.

3.     Solar Energy:

Another remarkable discovery of carbon nanotubes it has the capacity to absorb more sun than normal and it add up the efficiency of up to 8.5% more which is an exciting achievement for the solar users.

4.     Hydrogen storage

Hydrogen gas is the alternative source of fuel especially for vehicles, Current storage methods involve cooling and condensing the H2 gas to a liquid state for storage which causes a loss of potential energy (25–45%) when compared to the energy associated with the gaseous state. Storage using SWNTs would allow one to keep the H2 in its gaseous state, thereby increasing the storage efficiency. This method allows for a volume to energy ratio slightly smaller to that of current gas powered vehicles, allowing for a slightly lower but comparable range.

5.     Water treatment

Carbon nanotubes also use to treat polluted water more efficiency and cleanly than the current method and it has the capacity to absorb all aromatic and aliphatic contaminants in water.

6.     Stealth

Carbon nanotubes has the capacity to absorb radar rays and pass it through with the same section if the planes have a carbon nanosheet on it, some of the countries done that practically but the formula, science and technology behind this remain undisclosed.

7.     Medical

It’s under research of carbon nanotubes in medical science and some experiment made which shown exceptional result such as tissue engineering, including bone, remove tumor from laser using nanotubes.

8.     Clothes

Carbon nanotubes have the capacity to move and roll it up like a paper therefore researchers thinking of using this in clothing fabrics if it happened then the different era of wearing clothing would come.

9.     Other uses

Other uses of carbon nanotubes are still under observation and no conclusive evidence found to add them in this list, however there is a expectation that in future there will be a lot of uses of this carbon nanotubes that would change the world dramatically.
