Abstract
Polyaniline/WO3 nanofiber composite-based surface acoustic wave (SAW) gas sensor has been investigated towards hydrogen (H2). Chemical oxidative polymerization of aniline was employed to synthesize polyaniline nanofibers with WO3 nanoparticles. The nanocomposite was deposited onto a layered ZnO/64° 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 7 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.
