摘要：

The present paper reports about the conducting polyaniline-poly(acrylonitrile-butadiene-styrene) blend films as a sensor material for aqueous ammonia. The change in resistance value of these blend films on exposure to different concentrations of aqueous ammonia shows its utility as a sensor material. The conducting blend films on exposure to 10(-4), 10(-5) and 10(-6)N aqueous ammonia show a well-defined response behaviour and this aspect has been utilized in designing the ammonia sensor.
