Abstract
The present paper reports about polyaniline-(acrylonitrile-butadiene-sty co mposite film as a sensor material for aqueous ammonia. The resistance chang e of the composite film on exposure to different concentrations of aqueous ammonia shows its utility as a sensor material. The composite film on expos ure to 10(-4) and 10(-5) N aqueous ammonia shows a well-defined response be haviour and this aspect has been utilized in designing the ammonia sensor.
