Abstract
Presented here are the preliminary results concerning an
investigations of a novel bilayer sensor structure of polyaniline
and Nafion as a toxic gas sensors in a Surface Acoustic Wave system.
The investigations were performed with different concentrations of
the various toxic gases like SO2, CO, H2S and ammonia
(NH3) in synthetic dry air. The prototype polyaniline and
nafion bilayer structure has been manufactured by two deposition
technologies: 180 nm of PANI by PVD technology and thin Nafion film
by spin coating technology and specific process of annealing. A good
interaction with various concentrations of ammonia for the bilayer
structure (PANI film with Nafion) has been observed
