Carbon Nanotube Dispersion
Carbon nanotubes have incredible mechanical and electrical properties and are required to prompt numerous new materials and modern applications, yet to exploit their qualities they should be exceedingly and exclusively dispersed.

Carbon Nanotube Dispersion Equipment:
Ultrasonic dispersion device: ideal for laboratory-scale, low-viscosity media to disperse carbon nanotubes;
(2) Grinding dispersion equipment: suitable for large-scale dispersion of carbon nanotubes, middle-viscosity media to disperse carbon nanotubes;
(3) Combination method: “first grinding, second ultrasonic dispersion ” can be efficiently and stably to disperse carbon nanotubes.
MWNTs are highly conductive when properly integrated into a composite structure. The outer wall alone is conducting, the inner walls are not significant to conductivity. MWNTs have a high aspect ratio with lengths typically more than 100 times the diameter, and much higher. Their performance and application are based not just on aspect ratio, but also on the degree of entanglement and the straightness of the tubes, which in turn is a function of both the degree and dimension of defects in the tubes.
MWNTs are suitable for various applications due to its high conductivity and high aspect ratio. The needed conductivity level can be achieved with much lesser loadings than for conventional solutions such as metal particulates or carbon black. Applications are electrostatic discharge protection in wafer processing fabrication, antistatic elastomeric and plastic components for automobile fuel line components, plastics rendered conductive to enable electrostatic spray painting of automobile body parts, RFI shielding materials, etc.
