      Abstract:

      The effects of AC field strength and AC frequency on the density   of dielectrophoretically deposited multi-walled carbon nanotubes   (MWCNTs) were investigated and explained in terms of existing   theory. We show that while both parameters can be used to control   deposition density, the experimentally observed frequency trend   can not be explained by the theoretical   Clausius–Mossotti factors. We demonstrate the ability to   make surfactant-free dispersions of long, difficult to disperse   MWCNTs and use them with dielectrophoresis to make clean, single   and few connections between electrodes.
