Abstract
For the purpose of increasing the dispersibility and thermal conductivity of fluid containing nanoparticles, raw multi-walled carbon nanotubes (MWCNTs) were treated by strong acids. The purified structures were dispersed into aqueous solution by using wet grinding conditions at various rotation speeds (300–600rpm) merged with ultrasonication. The particle size analyzer reveals that the agglomerated size of ground particles at rotation speed of 300rpm was 39.811μm. Nevertheless, the agglomerated size of particles significantly decreased to 11.482μm after grinding at rotation speed of 600rpm. The maximum absorbance (4.0 abs at wavelength of 300nm) and highest thermal conductivity (0.6074W/mk at 30°C) of the suspension corresponds to the grinding speed of 600rpm assisted by ultrasonication dispersion. From the overall results, grinding method with high rotation speed plays can be significantly increased both the dispersibility and thermal conductivity of MWCNTs in aqueous solution.
