Nanofillers, carbon nanotubes (CNTs), especially single-walled carbon nanotubes (SWNTs), have attracted a great deal of interest due to their low density, large aspect ratio, superior mechanical properties, and unique electrical and thermal conductivities [1-4], They can find potential applications in many fields, such as chemical sensing, gas storage, field emission, scanning microscopy, catalysis, and composite materials.

Another area of intense interest in conducting-polymer nanomaterials for chemical sensing is their combination with carbon nanostructures, most particularly carbon nanotubes, either single-walled (SWNT) or multiwaUed (MWNT). This again reflects the desire to combine the beneficial properties of both types of material to create new combinations with novel properties. CNTs empart high conductivity and high aspect ratios, which yield low percolation thresholds with nanodimensional stmctural order. This has led to their application as chemical sensors. However, CNT-based devices are difficult to fabricate, an issue which may be overcome by their dispersion in a conductive polymeric matrix.
