Product Overview

The preparation of carbon nanotubes by the CVD method is widely used with the advantages of mature method and high yield. However, the preparation of carbon nanotubes by CVD often requires the introduction of a catalyst, and the nanotubes grow in radial and axial directions with the catalyst particles as the centre. The catalyst is difficult to be removed, which becomes an important factor to restrict the improvement of the purity of carbon tubes, and will limit the application of carbon tubes to a certain extent. Graphitised carbon tubes are obtained by high-temperature treatment of ordinary carbon tubes in an inert atmosphere, which can effectively remove catalysts and other impurities, effectively improve the high purity of carbon tubes, reduce defects, and effectively improve their microstructure in order to obtain good electrical conductivity, thermal conductivity, mechanics and other properties. The higher the degree of graphitisation, the better the crystallinity of carbon nanotubes, and the thermal stability and electrical conductivity are usually better.

Product characteristics

High purity: Most of the metal impurities are removed under high temperature treatment of the carbon tube.

It has good flexibility and elasticity and can withstand large deformation without breaking. For example, in some micro-mechanical parts, complex movements can be achieved using their flexibility.

Electrical properties:

It has good electrical conductivity, and the electrical conductivity can be close to copper.

Exhibit unique quantum conductivity properties. For example, in nanoelectronic devices, their conductance characteristics contribute to precise current control.

Thermal properties:

The thermal conductivity is very high and can effectively conduct heat.

Good thermal stability, can still maintain the stability of structure and performance in high temperature environment. This makes it a potential application in highly efficient cooling materials, such as the cooling components of high-power electronic devices.

Chemical properties:

High chemical stability, not easy to react in most chemical environments.

The surface can be chemically modified to meet different application requirements. For example, it can be better dispersed in certain solvents or substrates through chemical modifications.

Optical properties:

It has unique optical absorption and emission characteristics in the near infrared and visible regions.

It can be used to make optical sensors and light-emitting devices.


Application Fields

Battery electrodes: Graphitised carbon nanotubes can be used as a conductive agent in lithium batteries to improve the conductivity and cycle life of the battery. 

Composite materials: by adding graphitised carbon nanotubes to matrices such as polymers, metals or ceramics, composite materials with high strength, high electrical conductivity and high thermal conductivity can be prepared. 

Electronic devices: Integrated circuits and display backplane driver devices based on semiconductor-type graphitised carbon nanotubes are being developed. 

Sensor devices: graphitised carbon nanotubes are characterised by high sensitivity and fast response, and can be used to prepare gas sensors, biosensors and so on. 

Electric heating devices: using graphitised carbon nanotubes' good electrical conductivity and electro-thermal conversion properties, highly efficient electric heating devices can be prepared.

Perfect Mouse & Keyboard Combo!
Style: Combo, Color: Rose, Size: 1 Pack
I love this combo so much I bought one for home and one for the office. I’m very picky when it comes to a mouse and a keyboard. The clicking sound drives me crazy. This mouse is very quiet and the keyboard is easy to type on. I love that the keyboard includes shortcut keys (calculator, volume control, etc.) and they actually work unlike others. I also appreciate the windows key - makes it easy to lock your computer when you’re away. The color is so pretty! Absolutely love the shade of pink. Highly recommend this product! Logitech is hands down the best!

Reliable and lasts forever Best budget option
Style: Combo, Color: Black, Size: 1 Pack, Style: Combo, Color: Black, Size: 1 Pack
I had this same model a long time ago and it lasted forever, I only had to get a new one because I lost the USB receiver, so I know for a fact they are very durable. For the price, you can't beat the compatibility you just plug it in and it works instantly. The appearance is very simple, it's not the most attractive or pretty keyboard since it has no lighting or fancy features, but it's built to last. The noise level is fine for a membrane keyboard, not too loud. In terms of ergonomics, it feels comfortable enough for daily work and the color is just the standard black that goes with everything. The best part is the battery life, it lasts months without needing a change.

Very comfortable to use
Style: Combo, Color: Rose, Size: 1 Pack
This is a nice keyboard/mouse for the money. I ordered it in pink because it will help me to keep it separate from others I have. I have a tendency to forget which mouse goes with which keyboard. The color makes all the difference. In addition this works well and has a light up indicator for the caps lock which my older one does not. That was annoying to look up and see that everything was in caps by mistake. Good product.

Works great, very happy with it!
Style: Combo, Color: Black, Size: 1 Pack
I really like this keyboard and mouse combo! It arrived in perfect condition and works exactly like it should. Setting it up was incredibly easy- you just plug in the little USB receiver and you are ready to go. ​The keyboard is comfortable to type on, the mouse is smooth, and the wireless connection has been flawless. If you need a reliable, no-nonsense setup for daily use, this is a great choice. Highly recommend!
