The possible applications of carbon nanotubes range from electronics, field emission displays, energy storage devices, functional fillers in composites, and biomedical applications. These have attracted both industrial and academic interest. However, due to the gap between basic research and the requirements of realworld applications, small nanotubes are facing technical difficulties such as dispersion, chirality selection, and handling. Therefore, it is important to smoothly and efficiently transfer the basic findings to industries to commercialize the novel technologies rapidly.

1 Introduction

Carbon nanotubes (CNTs) describe a family of nanomaterials made up entirely of carbon. In this family, multi-walled carbon nanotubes (MWCNTs) are of special interest for the industry and will be the subject of this paper. Structurally MWCNTs consist of multiple layers of graphite superimposed and rolled in on themselves to form a tubular shape.

2 Improved Properties

Such cylindrical graphitic polymeric structures have novel or improved properties that make them potentially useful in a wide variety of applications in electronics, optics and other fields of materials science. Carbon nanotubes are endowed with exceptionally high material properties, very close to their theoretical limits, such as electrical and thermal conductivity, strength, stiffness, and toughness. Moreover, MWCNTs are polymers of pure carbon and can be reacted and manipulated using the rich chemistry of carbon. This provides opportunity to modify the structure and to optimise solubility and dispersion, allowing innovative applications in materials, electronics, chemical processing and energy management, to name just a few. In summary, three properties of MWCNTs are specifically interesting for the industry: the electrical conductivity (as conductive as copper), their mechanical strength (Up to 15 to 20 times stronger than steel and 5 times lighter) and their thermal conductivity (same as that of diamond and more than five times that of copper). A combination of these impressive properties enables a whole new variety of useful and beneficial applications.

3 Conclusion

Carbon nanotubes are endowed with exceptionally high material properties, very close to their theoretical limits. A combination of these impressive properties enables a whole new variety of useful and beneficial applications. Depending of the amount of R&D efforts necessary to bring a particular product to the market, it can be differentiated between short, mid and long-term applications. Current or short-term applications are often based on the use of MWCNTs as a superior replacement of electrically conductive carbon blacks. This is especially advantageous in the automotive and electronic industries. New structural composite materials based on CNT reinforced thermoplastics combine low density and strong mechanical properties. Currently almost every sports item on the market can be improved by using CNT. This will open the way to new developments in particular by replacing metals in various 5 Page 5 / 6 mechanical applications where a weight reduction could save energy, like in automotive industry. On the medium to long-term a wide range of industrial sectors may benefit from the use of CNT. Due to the nature of some of these industries, more technical testing and longer certification time will be required before a market entry is possible. Improved mechanical properties of epoxy–carbon fiber composites can be used for wind power generators and in the aircraft industry. From improved textiles to electrical conductive ink for printable circuits, the range of impacted industries is staggering.

Description:

Conceptually, the structure of a SWCNT is a one-atom-thick layer of graphite, called graphene, wrapped into a seamless cylinder with either open or closed ends. As their name implies, MWCNTs consist of multiple concentric layers of graphene that form a tube shape.

By themselves, CNTs can be metallic or semi-conducting, and are uniquely strong. The many applications for CNTs are based on their unique structure, although some can use either MWCNTs or SWCNTs. MWCNTs are used today in conducting polymers; for example, in electrostatic spray operations. Due to their unique features, SWCNT are required for some key electronic applications such as memory, semiconductor components and transparent conducting films for touch screens, displays, solar cells and other devices. These and other applications were highlighted in “Carbon Nanotubes:

High Conductive Material MWCNT Multi Walled Carbon Nanotubes

1. Carbon nanotubes is the nano grade tubular graphite crystals, which consists of monolayer or multilayer flakegraphite that surround the center shaft according to certain spiral angle curly and into the seamless cylindrical tube. Because of special construction, it has many special properties and can be used in electronics, machinery, medicine, energy, chemicals, optics and other fields of materials science, as well as potential uses in architectural fields. They exhibit extraordinary strength and unique electrical properties, and are efficient thermal conductors.

2. The strength and flexibility of carbon nanotubes make them of potential use in controlling other nanoscale structures, which suggests they will have an important role in nanotechnology engineering.

3. Due to the difference of its diameter and helix angle, a carbon nanotube can be metallic attribute or semi-conductive attribute. So, can use it to make molecular-scale diode, and the diode will be as small as nanometer which is much smaller than the universal one at present.

4. Carbon nanotubes has the highest strength, which is much stronger than the steel. At the same time, carbon nanotube is very light in weight, which is only one tenth of the steel.

About Nanoshel Nanomaterial

Nanoshel LLC is a Wilmington, Delaware based nanotechnology company specializing in the commercialization of wide range of Nanoparticles and innovative materials of 21st century. Nanoshel is revolutionizing nanomaterials where traditional materials fall short.

Since 2005, Nanoshel has been exploring markets, developing innovative technologies, and providing breakthrough solutions using our Nanomaterials expertise. What’s interesting about materials on the Nano Scale – Contrary to popular belief is that size really does matter. That’s because when familiar materials are reduced to Nano proportions, they begin to develop odd properties. For example, plastics can conduct electricity, gold particles can appear red or green and solids can turn into liquids almost spontaneously at room temperature. While not all material is subject to change, the manipulation of such Nano change is a cornerstone of nanotechnology research.

At the Nano scale, substances may behave differently or better compared to the same substances at macro sizes. For instance, Gold can change Colour, Carbon can conduct heat and electricity better Silver has improved antimicrobial properties. Other changes that occur to substances at the Nano scale can include: Becoming super-elastic, Becoming more chemically reactive, Getting physically stronger or weaker, and Being able to cope with massive changes in temperature and pressure. It’s because of these unique properties that nanotechnology could be used in such a huge range of products.
