Thin Walled Carbon Nanotubes – TWNTs
Thin Walled Carbon Nanotubes -TWNTs are produced by methane catalytic decomposition over Cobalt based catalyst (CCVD) and then are oxidized in an air atmosphere. There is almost no amorphous carbon in this product. TWNTs have a high aspect ratio which increases conductivity and mechanical properties. Thin Walled Carbon Nanotubes have a high ignition temperature and the temperature can often reach 620°C before they burn off. TWNTs can be used to make transparent conductive films or other research & industrial application. The TWNTs-based Transparent Conductive Films can reach less than 200 ohm/sq sheet resistance with more than 80% transparency. Their purity is 90wt%, outer diameter is 3-5nm, & the length is 5-30um.

Thin Walled Carbon Nanotubes Applications
Thin Walled Carbon Nanotubes are well suited for CNT-based Transparent Conductive Films for the touch screen, flat panel display, OLED, and thin-film solar industries. Compared with traditional indium tin oxide (ITO) coated films, the TWNTs-based transparent Conductive Films have:
1. More mechanically robust for longer lifetime
2. Broader and more color neutral transmittance.
3. Higher levels of sheet resistance without losing uniformity
4. Lower cost
Thin Walled Carbon Nanotubes can be dispersed into solvents by ultrasonication and high shear methods. Generally surfactants are used to stabilize the dispersions. Try some of our Thin Walled Carbon Nanotubes today!
