Abstract

Polyaniline nanofibers are very promising chemical sensor materials. Using a chemiresistor platform, the resistance of polyaniline nanofibers can be monitored as the device is exposed to chemical vapors. Advantages of polyaniline nanofibers include huge surface area, fast time response, and relatively well studied chemistry and physics associated with structural modifications. Two examples are given showing clear responses of polyaniline nanofibar films to 0.9 ppm of ammonia and 18 ppm of nitromethane vapor. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
