Because nobody wants an unpure carbon nanotube
One possible use for carbon nanotubes is in advanced materials for building strong and lightweight structures, such as in aerospace and construction. They could also be used in electronics for high-performance electrical applications due to their excellent conductivity.
The term "nano" in carbon nanotubes refers to their extremely small size, typically on the nanometer scale (1 to 100 nanometers in diameter). This nanostructure gives carbon nanotubes unique properties, such as exceptional strength, lightweight, and electrical conductivity. Their small size also allows them to exhibit quantum mechanical effects, making them valuable in various applications, including nanotechnology, electronics, and materials science.
A carbon nanotube can be compared to the fullerenes, a group of spherical carbon allotropes (allotropes are different forms of a single element).The key difference is that the fullerenes are spherical in shape whereas carbon nanotubes resemble a fullerene network that has been stretched into a cylindrical shape. Furthermore, nanotubes contain more carbon atoms than most fullerenes do.
The concept of carbon nanotubes was first proposed by Sumio Iijima in 1991, when he observed cylindrical carbon molecules in soot particles.
Tiny hollow tubes made up of carbon atoms are called carbon nanotubes. They have exceptional strength, electrical conductivity, and thermal conductivity due to their unique structure, making them promising materials for various applications in nanotechnology, electronics, and materials science.
Carbon remain carbon.

Although there are numerous instances of people observing carbon nanotubes, most literature credits Sumio Iijima as the discoverer of carbon nanotubes.
the structure of nanotubes are carbon atoms joint together covalently to form a long tube.
No. Paper is cellulose, a carbohydrate usually derived from plant material. Carbon nanotubes are a variant of pure carbon that are used in a variety of high-strength materials.
Nanotubes are typically made from carbon atoms arranged in a cylindrical structure. Carbon nanotubes can have different properties depending on their structure and can be single-walled or multi-walled. They are known for their strength, flexibility, and thermal conductivity.
carbon nanotubes
Strength:Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.Hardness:Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation.
This technology is being explored as an option for body armor, but there are no body armor products using carbon nanotubes as yet.
Carbon can form diamond, graphite, amorphous carbon, nanotubes, fullerenes, etc.
Metals such as iron, zinc, lead, and copper can be purified from their ores by heating them with carbon. The carbon reduces the metal oxide to the elemental metal, which can then be separated and purified.
