Abstract
The concepts and calculation models of conventional dielectrophoresis(DEP)and traveling wave dielectrophoresis are introduced.The roles of dielectrophoretic force,dragging force from liquid,and Brownian motion in dielectrophoretic assembly of carbon nanotubes(CNTs)are analyzed.The current mathematical models for CNT assembly by DEP are reviewed.The effects of DEP parameters such as the concentration of the CNT suspension,the assembling time,the magnitude and frequency of the applied voltage,the geometry and spacing of electrodes on the DEP assembly are summarized.
