Outline of Final Research Achievements

In these studies, dispersed carbon nanofibers(CNFs) and carbon nanotubes(CNTs) in an uncured resin have been aligned by applying traveling electric field in a multiple electrode. In the primary study, two ctenoid-shape electrodes were symmetrically located. The CNFs in the long and narrow space between the ctenoid-shape electrodes were aligned to the longitudinal direction of the space. The applied voltages were successively and cyclically switched to the longitudinal direction.
In the following studies, the CNTs and resin suspension coated on a cover glass, and rectangular and six-phase voltages were applied to the multiple-electrode under the cover glass. The CNTs in uncured ultraviolet ray curing resin suspension were aligned in the whole area. After the rotation ceased, UV rays were irradiated to the suspension for resin curing. The electrical resistivities of the composites were measured in parallel and vertical directions to the aligned carbon nanotubes.
