EN Presented here are the preliminary results concerning a polyaniline thin films investigations in a Surface Acoustic Wave dual-delay line and electric systems. The polyaniline films has been prepared by an open-boat, physical vapor deposition (PVD) process using chemically prepared polyaniline powder as starting material. These films were simultaneously formed in a one of the SAW dual delay lines and on the interdigital electrodes of the glass substrate for electric resistance measurements. The thickness of the polyaniline films was about 100 nm. These polyaniline films have been investigated from the point of view their sensitivity towards: nitrogen dioxide, sulphur dioxide, ammonia, H2S, carbon monoxide and hydrogen gases with different concentrations in dry air. Preliminary measurements of this two polyaniline films have been performed simultaneously in the same chamber for this same measurement conditions using an acoustic and electric methods.
