The films of polyaniline nanofibers were deposited on interdigitated array electrodes by drop casting method. The ammonia gas sensing mechanism arises from the deprotonation process of acid doped polyaniline. The sensors exhibited the sensitivity of 1.06 and response time of 10s for 50ppm of ammonia gas. Such high sensitivity and fast response are attributed to the large surface-to-volume ratio and interconnected network structures. These results suggest that polyaniline nanofibers are promising materials for ammonia gas sensors with high performance.
