Abstract: In the present work, room temperature polyaniline-polyvinylalcohol (PANI-PVA) composite-based flexible ammonia sensor has been fabricated. The PANI-PVA composite films were synthesized by an in situ chemical polymerization of aniline in presence of PVA. The PANI-PVA composite-based flexible ammonia sensor shows better ammonia sensing properties than pure PANI. The sensor with 4 % PVA exhibits excellent sensing characteristics such as rapid response (~50 s to 4000 ppm), fast recovery (~90 s for 4000 ppm) and good reproducibility.
