Abstract :
A Polyaniline/In2O3 nanofiber composite based surface acoustic wave (SAW) gas sensor has been developed. Chemical oxidative polymerization of aniline was employed to synthesize polyaniline nanofibers with lIn2O3 nanoparticles. The nanocomposite was deposited onto a layered ZnO/64deg YX LiNbo3 SAW transducer. The sensor was exposed to various concentrations of H2 gas and operated at room temperature. The sensor response was found to be 11 kHz towards 1% of H2 in synthetic air. A fast response and recovery with good repeatability in a stable baseline condition were observed at room temperature.
