This study sought to align multiwalled carbon nanotubes in uncured ultraviolet ray curing resin suspension by applying traveling electric field in the whole area. The suspension coated on a 18mm × 18mm size cover glass and the coated cover glass were put on the multiple-electrode which was constructed with 24 long and slender electrodes. Rectangular and six-phase voltages were applied to the multiple-electrode. The applied voltage in one electrode had the phase differences of ±60 degrees among the voltages applied to the both side electrodes. The multiwalled carbon nanotubes in the suspension were rotated to the direction perpendicular to the electrodes. After the rotation ceased, UV rays were irradiated to the suspension for resin curing. In this way, aligned carbon nanotubes/ ultraviolet curing resin composites were produced. The electrical resistivities of the composites were measured in parallel and vertical directions to the aligned carbon nanotubes. In the latter half of this paper, the carbon nanotubes alignment was simulated under the experimental condition based on the method proposed by the author. Furthermore, the influence of the relative permittivity of the suspension on the fluctuation of the carbon nanotube orientation was theoretically clarified.
