Carbon nanotubes application:
1. The fabrication of microelectronic components and circuits, carbon nanotubes having electron field emission characteristics, while samples showed low operating voltage and high current stability. This manufacturing method with the current semiconductor production process is the same, so the promotion of this technology can be applied to promote the development of microelectronics technology nanotube devices.
2. supercapacitor: carbon nanotubes large specific surface area, high crystallinity, good conductivity, pore size can be controlled by synthetic process, so it is an ideal electric double layer capacitor electrode material. Carbon nanotubes are known supercapacitors maximum capacity capacitor.
3. Sensor: Sensor single-walled carbon nanotubes have a faster response and higher sensitivity. Single-walled carbon nanotube sensor manufacturing is not limited to a specific gas monitoring, experimental data have shown that it has a special performance in a variety of types of sensors.
4. The hydrogen storage material: The surface properties of the carbon nanotubes and hydrogen determines its interaction, the use of concentrated nitric acid and NaOH solutions were surface-treated carbon nanotubes, which greatly increases the surface area and surface activity, making hydrogen storage performance is much more than ordinary hydrogen storage materials.
5. catalyze chemical reactions: carbon nanotube modified electrode also showed strong catalytic ability, studies have shown that multi-walled carbon nanotube electrode carboxyl group of the compound (cysteine and glutathione) modified It has significant electrical catalysis.
6. The fuel cell: a nanotube is a new fuel cell vehicle power source the most development potential of this fuel cell generates electricity by consuming hydrogen, the exhaust gas is water vapor, so there is no pollution.
