We report the fabrication of a novel gas sensor that utilizes electrical resistance changes in electrically conductive polyaniline (PANI) and single-walled carbon nanotube (SWNT) composite materials and its sensing property when NH3 and CO gases co-existed. In addition, we investigated the concentration dependence of electrical properties of the PANI/SWNT composite material at room temperature using real-time monitoring. To improve the gas sensor properties, we deposited PANI using a drop-casting method to warp the PANI surrounding the SWNT. The PANI/SWNT composite material sensors showed a faster response to NH3 gas than CO gas. The CO gas increased the composite conductance, while the NH3 gas had the opposite effect.

Keywords:gas sensors;electrical resistance;conducting polymer;single-walled carbon nanotubes (SWNTs);unsafe gases.
