Best Way To Reduce The "E.S.D" Defects
The term static electrification is often used.
It refer to the accumulation of static electricity generated on an object.
Actually, this amount of charge that affect the trouble caused by static electricity.
<Table>The criterion of resistivity and electrification of an object* The unit of the conductivity is S(siemens )/m
|Volume Resistivity[Ω,m ]||104||106||108||1010||1012||1014|
|Surface Resistivity [Ω]||106||108||1010||1012||1014||1016|
|Ease of Electrification||High||Little||Not||Little||Middle||High||Too High|
|The Speed Of Decrement||Instant||Instant||Instant||A few seconds||A few minutes||Tens of minutes||No decrement|
CNT (Carbon nano tube) is a tube-shaped and nanometer-sized diameter of carbon. It has features such as high thermal / electrical conductivity, high strength and chemical stability.
When even a small amount of carbon nanotube is mixed with existing polymer materials greatly improved in mechanical properties and electrical conductivity etc.
The electrical conductivity characteristic of the carbon nanotube is increasing dispersion speed of charge. In addition, the carbon nanotube is an eliminating static electricity substance that can be discharged immediately about triboelectric.
When raised the electric current with constant interval to the carbon nanotube plate in a vacuum,
It shows that exported electric field has been detected in the around.
It appears that carbon nanotube has its own electrostatic discharge effect.
There is no specific state in the low electric current. While gradually rising up to 3.7 V/μm, the electric current reaches the maximum electric current value of 2.9mA.
And the breakdown occurs with its own emission at this moment.
