SINGLE-WALLED carbon nanotubes (SWNTs) are nanometer-diameter cylinders consisting of a single graphene sheet wrapped up to form a tube. Since their discovery in the early 1990s and there has been intense activity exploring the electrical properties of these systems and their potential applications in electronics. Experiments and theory have shown that these tubes can be either metals or semiconductors, and their electrical properties can rival, or even exceed, the best metals or semiconductors known. The remarkable electrical properties of SWNTs stem from the unusual electronic structure of the two-dimensional material, graphene, from which they are constructed. Graphene—a single atomic layer of graphite consists of a 2-D honeycomb structure of sp bonded carbon atoms.

SPECIFICATION:

1 Introduction

SWCNT are surely the carbon nanotubes variant with the most interesting combination of physical properties. They show world records in mechanical, electrical and thermal properties. For most of the time, there was no guarantee for a sufficient availability of this outstanding material. In the meantime, however, increasingly larger quantities of SWCNT have entered the market, which enable the development of attractive applications. Therefore the worldwide fascination in connection with carbon nanotubes as such may finally become reality with SWCNT. Currently, the Fraunhofer IWS Dresden is one of the few institutes worldwide, which can synthesize and offerSWCNT at a kg scale for application developments.

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:

Single-wall Nanotubes (SWNT)

Single-wall nanotubes (SWNT) are tubes of graphite that are normally capped at the ends. They have a single cylindrical wall. The structure of a SWNT can be visualized as a layer of graphite, a single atom thick, called graphene, which is rolled into a seamless cylinder.

Most SWNT typically have a diameter of close to 1 nm. The tube length, however, can be many thousands of times longer.

SWNT are more pliable yet harder to make than MWNT. They can be twisted, flattened, and bent into small circles or around sharp bends without breaking.

SWNT have unique electronic and mechanical properties which can be used in numerous applications, such as field-emission displays, nanocomposite materials, nanosensors, and logic elements. These materials are on the leading-edge of electronic fabrication, and are expected to play a major role in the next generation of miniaturized electronics.

Application:

Many improvements of basic materials properties can be achieved by using carbon nanotubes in polymers and metals as fillers. Especially the SWCNT of the Fraunhofer IWS Dresden are constantly optimized to enable an adjustment of the desired physical and mechanical properties of the final composite product with extremely low additional quantities of SWCNT. For example, transparent and flexible polymer electrodes, anti-static surface coatings, photovoltaics, sensors and actuators technology as well as printed electronic circuits are possible. Current IWS development highlights include polymer-based conductive, transparent electrodes and flexible electrodes for dielectric actuators with high conductivity and robustness.

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.
