摘要：
The present paper reports about polyaniline-(acrylonitrile-butadiene-sty composite film as a sensor material for aqueous ammonia. The resistance change of the composite film on exposure to different concentrations of aqueous ammonia shows its utility as a sensor material. The composite film on exposure to 10(-4) and 10(-5) N aqueous ammonia shows a well-defined response behaviour and this aspect has been utilized in designing the ammonia sensor.
