Abstract

The assembly of multiwalled carbon nanotube (MWCNT) films through dielectrophoresis is described and the electrical response of aligned and randomly oriented MWCNT films to temperature variations is evaluated. The resistance of the randomly oriented MWCNT films was found to decrease exponentially with temperature. The decrease was less marked when the films were annealed and kept dehydrated during the electrical measurements. Alignment of MWCNTs led to an apparent reduction in the electrical response of the films with temperature changes and a small measurement-to-measurement variability, suggesting that dielectrophoresis-aligned MWCNT films would be more reproducible detectors in applications exploiting CNT-mediated electronic sensing.
