Introduction

Carbon nanotubes are allotropes of carbon which take the form of cylindrical tubes. They have novel properties that make them potentially useful in a variety of applications in nanotechnology, optics, electronics, and other fields of materials science. Carbon nanotubes are categorized into two main types: single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) .

Single-walled Carbon Nanotubes

SWCNTs are produced through the Arc- discharge process. They have a purity of about 95 to 98wt% and include roughly 92 to 95wt% of carbon nano particles. SWCNT has a diameter of about 0.7 to 2nm and forms a bundle measuring 8nm. It does not require any separate refinery process.

Characteristics and Applications of Single-walled Carbon Nanotubes

SWCNTs have excellent mechanical strength with superior heat and electric conductivity. They have high crystallinity and aspect ratio together with excellent Arc- discharge element characteristics.

SWCNTs are used in chemical sensors, nano biomaterial, conductive heating film, conductive transparent electrode, conductive nanoink, nano device, and display (backlight, flat lamp and field emitter).

Multi-walled Carbon Nanotubes

MWCNT is produced by means of thermal CVD process and does not need a separate refinery process. Its diameter ranges from 10 to 30nm and has a purity of at least 95%. MWCNT are suitable for polymer and CNT-metal composites.

Characteristics and Applications of Multi-walled Carbon Nanotubes

Similar to SWCNTs, MWCNTs have excellent mechanical strength with superior heat and electric conductivity. They also have high specific surface area, high crystallinity, and high length-to-diameter ratio.

Carbon nanotubes are used in a wide range of application such as chemical sensors, conducting paints, energy storage, and composite materials (ESD, heat exchanger, reinforced material and EMI shielding).

Since Nanoshel CNT (Figure 1) has large aspect ratio and excellent physical properties, they can convert a 3D network structure into thin films. This reinforces the popularity of CNT as an ideal material for transparent electrodes. When compared to the commonly used ITO electrodes, CNT transparent electrodes allow excellent flexibility, mass production of materials, and low production costs. In addition, CNT can also be applied to e-paper, flexible display, flat touch panels, as shown in Figure 2.

When applying CNT, it is important to maintain high crystalline, high purity, and mix of CNT. In order to improve these factors, a number of studies have been carried out across the globe.

Properties of Nanoshel Carbon Nanotubes

Nanoshel CNTs is a high-elasticity material based on the graphite crystal structure. It is a fibrous substance with high aspect ratio, high strength and high specific surface area with excellent heat and electric conducting properties. This material is also lightweight and environment friendly.

Conclusion

Nanoshel CNTs can be used in sports equipment such as tennis rackets, golf clubs, surfboards, baseball bats etc. Potential applications of these materials include military industry, textile industry, petrochemical engineering, chemical fiber and plastic, paints and adhesives, medical and health, ceramic industry, environment protection, battery, daily health products, energy saving, steelmaking, and agriculture.
