Abstract

Thin films containing single-wall carbon nanotubes (SWCNTs) have been prepared using the inkjet printing (IJP) technique. Atomic force microscopy (AFM) has been used to investigate the morphology of these layers. The inkjet printed films consisted of small, randomly-oriented islands of nanotubes, the topography of which was dependent on the nature of the substrate surface. The in-plane electrical characteristics of the films were measured at room temperature. The current versus voltage data exhibited non-linear behaviour, which could be fitted to the theoretical model for Poole-Frenkel conductivity. Preliminary measurements are also reported on the use of the thin layers to detect alcohol vapour.
