Double-walled carbon nanotubes DWCNTs

There is a great demand for super-strong, super-tough, and super-fatigue-resistant materials in many fields such as aerospace, military equipment, bulletproof vests, large bridges, sports equipment, artificial muscles, etc. Carbon nanotubes are typical one-dimensional nanomaterials and are also the materials with the highest known mechanical strength and toughness. Their macroscopic strength and toughness are higher than the currently widely used carbon fibers and aramid fibers. In addition to enhancing strength and toughness, double-walled carbon nanotubes DWCNT can also be used in gas sensors....

DWCNT double-walled carbon nanotubes for gas sensors

Specifications: diameter: 2-5nm, length: short tube 1-2um, long tube 5-20um, purity: >95%

There is a great demand for super-strong, super-tough, and super-fatigue-resistant materials in many fields such as aerospace, military equipment, bulletproof vests, large bridges, sports equipment, artificial muscles, etc. Carbon nanotubes are typical one-dimensional nanomaterials and are also the materials with the highest known mechanical strength and toughness. Their macroscopic strength and toughness are higher than the currently widely used carbon fibers and aramid fibers.

In addition to enhancing strength and toughness, double-walled carbon nanotubes DWCNT can also be used in gas sensors.

Double-walled carbon nanotubes DWCNT for gas sensors:

1. Carbon nanotube gas sensors have many characteristics such as high sensitivity, fast response, small size, low power consumption and low operating temperature.

2. Carbon nanotubes are one of the ideal nanomaterials for the development of solid-state sensor technology. Carbon nanotube sensors with huge aspect ratios and specific surface areas can become highly sensitive material layers and efficient conduction channels.

3. Carbon nanotubes are easily integrated into microelectronic devices, and sensors with multiple small sensor arrays can be manufactured.

4. Carbon nanotube gas sensors can work at room temperature; without heating devices, the volume of the sensor is reduced, and the power consumption of the sensor is reduced, thereby increasing the service life of the core components and extending the battery life of the sensor.

5. Carbon nanotube gas sensors have been able to analyze various important environmental gases in industry, environmental protection, physical security, medical testing, and defense and military fields.
