Applications of Carbon nanotubes

Technology is becoming advanced day by day. The new tools are used to create marvelous devices. It has been observed that new technical devices are becoming shorter and advanced with more fascinating features than used in the past tools. For example the computers were larger than room when developed first time. But know they are Compact and moving toward nanotechnology. Carbon nanotubes are also one of the latest inventions of micro technology. The nanotubes are very small and can be used in various fields.
They are widely used in the fields of optical communication, Electronic and nanotechnologies. Here presenting lists of the few applications of these new nanotubes.
• They have high tensile strength and strong resistance to breakage. They are used in flywheels, bridges and space elevators. This is only possible due to high tensile strength of the material.
• It is an effective material which is utilized in fire resistive products. It resists high temperature easily. The buckypaper provides more fire resistance due to the presence of thick layers of Carbon Fibers.
• Nanotubes electrically transparent films are now used as displays for computer, mobile phones and other devices. These are replacing techniques of LCD’s and touch screens with their electric conducting mono films.
• They are excellent products for the brushes of electric motors. The carbon black can be replaced with less brittle and stronger nanotubes. These are better than old brushes of motors in terms of lubricating. You can easily mold brushes made from carbon nanotubes.
• They are used to produce photocurrent in solar cells. As these are electrically transparent they allow light to pass through them. When light passes through the top layer of carbon nanotube films it produces photocurrent.
• These are considered as superconductors and efficient capacitors for storing energy
• Used as antennas for various electromagnetic devices.

The Unique Properties of carbon nanotubes

Carbon nanotubes are generally regarded as the single hardest materials known to man. A single walled nanotube is able to withstand a pressure that amounts to 24 GPa. It can withstand this pressure without having any kind of deformity and without seeming like it is being affected in anyway. Nanotubes are also known to have kinetic properties that make them get nested with each other. There is an outstanding telescoping property that they tend to display with time and this usually involves sliding of the inner core nanotube. This sliding occurs with very little or no friction at all and usually leads to rotational bearing.
When dealing with carbon nanotubes it is very vital to know that their electrical properties are very unique. The nanotube structure usually has an effect on the electrical properties of graphene owing to its electronic structure that is quite unique. There are however a number of exceptions in the general rule regarding the electrical properties of these nanotubes. Some superconductivity properties have also been registered with some of these nanotubes and although there are several other experiments that disagree with this assertion, these reports continue to create a stir among experts.
The thermal properties of carbon nanotubes are quite unique too because these nanotubes are mostly expected to have good conduction. Ballistic conduction is actually a property that is shown by the nanotubes as they go about their thermal conduction. Another vital issue in the properties of these nanotubes is the issue of toxicity. When dealing with nanotechnology, many experts have raised several questions about the toxicity of the nanotubes. This study and research is still in its early stages and there is quite a lot criticism still going on. It is expected that over the years the results will help to give experts a little more understanding of how these nanotubes deal with the question of toxicity.
