Abstract:
The separation of two different types of multi-walled carbon nanotubes is studied in a dielectrophoresis-based microchannel system in seven different solvents as the suspending medium. A simple model was developed to predict the behavior of the multi-walled carbon nanotubes in the above mentioned system. Then, the equations of motion for the multi-walled carbon nanotubes in that system were introduced and the effect of the suspending medium type on the fabrication parameters of dielectrophoretic system, such as applied voltage and inter electrode gap, was surveyed. The calculations indicate that the suspending medium has a direct influence on the design and optimization of dielectrophoretic systems. The geometrical separation of the carbon nanotubes is considered here, and it was found that the model predicts some advantages in separation and sorting multi-walled carbon nanotubes based on their diameter.
