Property of Conductive carbon nanotubes:
Multi-walled have high conductivity, big helical angle, after micron scale grinding,easy to disperse,more fine and smooth
1. C=C satble , excellent mechanical
2.High strength and great toughness
3. HighModulusGraphite
4.Electrical and thermal conductivity
5. Heat resistant and corrosion resistant
Application of carbon nanotube :
1. Carbon nanotube as conductive polymer plastic :
1.Good conductivity of carbon nanotubes, insulating polymer to obtain excellent conductivity
Widly use in vehicle fuel conveying system, fuel filter, semiconductor chips, and computer read/write head ,
antistatic device of the inner packing, auto conductive plastic parts manufacturing , electrostatic coating
2.high elasticity and of strength of extension carbon nanotubes ,
3. Electromagnetic radiation shielding
Use in human body electromagnetic radiation protection ,
electrical and electronic equipment electromagnetic shielding ( mobile phone, computer, microwave oven )
4. Microwave absorbing :
Use in military stealth materials: Aircraft, missiles and artillery, tanks
2.Carbon nanotube as Electrochemical devices
1. Super capacitor electrode : good discharge performance, within a few milliseconds will all stored energy release
Use in Hybrid electric vehicle ( provide energy faster and improve the battery life )
regulated voltage ofwind turbine system,small solar energy storage system
2. Manufacturing mechanical and electrical brake : working voltage of carbon nanotubes electromechanical brake only a few volts
3.Carbon nanotube as Hydrogen storage
Under room temperature and pressure, about two-thirds of the hydrogen released from carbon nanotubes, and can be repeatedly used
Use in the fuel cell system and electromobile hydrogen storge,
4.Carbon nanotube as Field emission devices
Field emission tube : Field Emission Display , Fluorescent lamp gas discharge tube ,X Ray , microwave generator , Carbon nanotubes flat-panel displays
5.Carbon nanotube as field effect transistors
Carbon nanotubes sensor size is very small sensitivity is extremely high
6. Carbon nanotube as catalyst carrier
