CNT carbon nanotubes cost, carbon nano tube wire,

double walled carbon nano tube

Specification ofdouble walled carbon nano tube

1. Out Diameter: 2-5nm2. Purity: CNTs: 91%3. Length: 1-2um & 5-20um

High thermal Stability: DWCNTs can bear thermally treated at 2000°C with no structural change.

Application of double walled carbon nano tube:

Double walled carbon nanotubes are mechanically, thermally, and structurally more stable than single walled CNTs. DWCNTs have greater structural,chemical, and oxidative stability, and higher bending resistance, better use for for applications multi-functional composites, electrochemical electrodes and/or additives, field emitters, and nano-sized semiconductor devices.They are as effective multifunctional fillers in producing tough, conductive transparent polymer films.

Double walled carbon nano tube are considered to be the final one-dimensional line on the basis of pure carbon. Double-walled carbon nanotube defect-free with a smooth surface with atomic precision on the nanometer manufacturing a bearing hope. DWNTs open at both ends, between the inner and outer layers of vibration in the axial direction can to GHZ level, is a good material for the preparation of nano-oscillator. Double walled carbon nano tubeare one-dimensional material between the important single-walled and multi-walled carbon nanotubes between the inner and outer layers of its chiral parameters and the inner and outer tube spacing relevant, between 0.33 nm and 0.42 nm, than Common-layer multi-walled carbon nanotubes spacing. Because of the double-walled carbon nanotubes between the inner and outer layers of weak interactions tube, which led to a double-walled carbon nanotubes have unique band structure, it can be expected to have unique electrical and optical properties.

Double-walled carbon nanotubes and single-walled carbon nanotube electrical properties similar performance as conductor at room temperature, while different from the multi-walled carbon nanotubes. With increasing temperature, double-walled carbon nanotube resistivity was reduced after the first rising trend, there is a minimum point resistivity. Double-walled carbon nanotube film from the semiconductor body transformation guide Tk characteristic temperature can reach 32 K, than a single single-walled carbon nanotube bundles 35 K lower.
