抄録

The influence of the shape and size of carbon nanotubes (CNTs) on the alignment of multi-wall CNTs was investigated. A CNT suspension with polyethylenimine (PEI) added as a dispersant showed stable dispersion. Stable CNT dispersion had a relatively high zeta potential value compared with poor dispersion. In addition, a strong magnetic field of 12 T was applied to the CNT suspension to investigate the alignment behavior of the CNTs. Good alignment of the CNTs according to the direction of the magnetic field was obtained. The degree of alignment depended on the shape and size of the CNTs, with the thick, straight CNTs showing better alignment than the thin, curved CNTs.
