Description
| - We have studied the gas sensing properties of five polyaniline-based materials—thick and thin polyaniline (PANI) films, nanocomposite films of PANI and single-wall and multi-wall carbon nanotubes, and PANI nanogranules embedded in a polyvinylpyrrolidone matrix. The films were deposited within the induction period of the polymerization process on gold interdigitated micro electrodes. Their sensitivity to ammonia, hydrogen, ethanol, methanol, and acetone was measured. The thin PANI film (100 nm thick) prepared by a lift-off process had the sensitivity to ammonia below 0.5 ppm, which was higher than that of nanocomposite films. Two materials – thick PANI film and nanocomposite film of PANI and multi-wall carbon nanotubes – exhibited a shallow minimum in the temperature dependence of resistance at 313 K and 319 K, which is a feature exploitable in practical applications, since the gas sensors should be insensitive to small temperature fluctuations at these temperatures.
