Induced Interaction of NH_4NO_3 with POLY(P-PHENYLENE VINYLENE) by Mean of Zeolite Y.

摘要

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.
