Carbon nanotubes(CNTs) are the most ideal functional fillers for heat dissipation coatings. Theoretical calculation shows that thethermal conductivity of single-walled carbon nanotubes(SWCNTs) is as high as 6600W/m.K under room temperature, while that of multi-walled carbon nanotubes(MWCNTs) is 3000W/m.K. CNT is one of the best known thermal conductivity materials in the world. The energy radiated or absorbed by an object is related to its temperature, surface area, blackness and other factors. CNTs is a one-dimensional nanomaterial with a large specific surface area and is known as the blackest substance in the world. The refractive index of it to light is only 0.045%, the absorption rate can reach more than 99.5%, and the radiation coefficient is close to 1.

Carbon nanotubes can be used in heat dissipation coatings, which can increase the surface emissivity of the coated material and radiate the temperature quickly and efficiently.
At the same time, it can make the surface of the coating have the function of dissipating static electricity, which can play the role of antistatic.
