Single Walled Carbon Nanotubes: Improve The Properties Of Your Materials
Today, science and technology has become far more advanced. Nano technology is the prime reason for bringing so many advancements in every field. When science deals with miniature products in nano scale, it calls itself, nanotechnology. The goal of this technology is to build machines, products and devices in the minutest size.
Carbon tubes are being used in many places and the above technology is used. Here, nano is three times smaller than micro. So, in this case you get single walled carbon nanotubes. These arrange themselves like a rope and are held close together by means of van der Waals forces. These rope-like tubes provide high quality and the properties of the materials increase thereby making it electrically conductive and many more.
Some of the important properties of Single Walled Carbon Nanotubes:
One of the best things about these tubes are they are the strongest and stiffest amongst many discovered products. This makes the single walled carbon nano tubes very special. In fact there are many manufacturing sectors that totally rely only on these tubes and gain a lot of profit out of their business. Some of its properties are discussed:
1. Hardness & Stiffness: These tubes can withstand a lot of pressure; up to 25Gpa. Important factor is they will not deform. Some bulk-walled modulus withstand up to 550Gpa which is equivalent to a diamond!
2. Kinetic Nature: Usually the single walled carbon nanotubes do not show much of kinetic property, when it is replaced with multi-walled, they are termed as molecular nanotechnology. This is used to create many useful machines. Friction is almost negligible and that’s why manufacturers rely on these tubes. They possess excellent kinetic property.
3. These possess a symmetrical structure and their unique electronic structure is termed as graphene. There is a maximum electrical conduction in a single-walled tubes. In special cases, scientists have even reported that these products exhibit intrinsic superconductivity. That’s the reason they are strongly used in the electrical industry. They are even treated as God in this field.
4. If we are talk about the optical and thermal property, then we must keep on talking. These tubes emit near-IR on photoexcitation. This helps in free electron flow and thereby making it ideal to be used in plenty of optical devices.
5. In terms of thermal property, they exhibit a property called ballistic conduction. This term means that it can transport electrons easily with just a negligible amount of electrical resistivity. Even this negligible factor is caused because of scattering alone.
6. They possess very strong bonds that typically match the bonds existed in alkaline and in the diamonds. No wonder they are the strongest and fittest of all the products.
7. Graphenated carbon nanotubes form as carbon fiber and they possess high surface area.
Splendid Facts about these Carbon Nanotubes that would Awe you
They have a very huge number of utilities. There are so many ways in which these tubes can be grown and some prime procedures are arc discharge process, laser ablation, CVD or chemical vapor deposition, process called plasma torch and through catalytic procedure. These are honeycomb like structures and possess unique properties that make it special in every way. The best part is it acts as semiconductor or as a metal.
Also, they have a very unique surface area which makes it resilient. Hence, they are used predominantly in pharma science as they show good strength and durability. In the nano electronics, they are the king. Since they show excellent electronic transport property they are used in making of flat panel displays and in field emission lamps. They can be chemically modified and can be made into single or multi-walled structure.
