The carbon black 112 is to generally refer to carbon simple substance particle, burns insufficient in carbon, will be detached from molecule, shape
At carbon black 112.In carbon black 112, carbon atom is arranged similarly to graphite, forms hexagon plane, usual 3~5 this
The level of sample forms a crystallite, due in each graphite level of 112 crystallite of carbon black, what the arrangement of carbon atom was ordered into, and
The arrangement of carbon atom is again unordered between adjacent level, so being called meta anthracite crystal.It could be theoretically argued that 112 loading of carbon black
Bigger, the density of carbon black particle or carbon black particle aggregate in dispersity is also bigger, and interparticle average distance is smaller,
The probability to contact with each other is higher, and the conductive path that carbon black particle or carbon black particle aggregate are formed is also more.The height of opposed polarity
Polymers and the polarity that carbon black 112 forms co-mixing system are bigger, and 112 critical volume fraction of carbon black is bigger, it is meant that system is led
Electrically decline, because very strong polar group is contained on 112 surface of carbon black, matrix polarity is big, and effect enhancing, at this moment intensity increases,
But the agglutination for interfering conducting particles itself, so that poorly conductive.But it is blended in multicomponent matrix resin with what carbon black 112 formed

Several nanometers.Carbon nanotube 113 has good conductive property, due to the structure of carbon nanotube 113 and the lamellar structure of graphite
It is identical, so having good electric property.Its electric conductivity of theoretical prediction depends on the helical angle of its caliber and tube wall.When
When the caliber of CNTs is greater than 6nm, electric conductivity decline；When caliber is less than 6nm, CNTs can be seen as with satisfactory electrical conductivity
The One-dimensional Quantum conducting wire of energy.In order to reach satisfactory electric conductivity, while meeting the mechanical property and creep-resistant property of material,
The weight ratio of the carbon nanotube 113 is 1%~2%.Preferably, the content of the carbon nanotube 12 is 1.5wt%.The carbon
The length of nanotube 113 should be 3 μm~5 μm, to improve its conductivity uniformity.Because the length of carbon nanotube 113 can reach
To a centimetre line, if too long, the uniformity of its dispersion can be reduced in mixed process, so that its conductive uniformity can be reduced,
And then its electrophoretic effects in electrophoresis process, the i.e. different flaw of electrophoresis thickness can be reduced.
The carbon fiber 114 be a kind of phosphorus content 95% or more high intensity, high modulus fibre tencel material
Material.It is to be piled up by organic fibers such as flake graphites along fiber axial direction, is obtained through carbonization and graphitization processing
