Chemical sensor technologies play an important role in development and improvement of public
health and environment through applications in many areas. Conducting polymers are unique among the
sensing materials known to us at present. They have many advantages over conventional metal sensors.
Poly(p-phenylenevinylene) (PPV) can serve as the active material in sensor devices because PPV possesses
good optical and electrical properties, and it can be synthesized by a relative simple technique. Zeolite is
chosen to be introduced into a polymer matrix in order to increase sensitivity toward ammonium nitrate gas.
This work will focus on the effect of Si/Al ratio and cation type on the electrical conductivity sensitivity
towards the target gas.
