Abstract

Polyaniline/WO 3 nanofiber composite-based surface acoustic wave (SAW) gas sensor has been investigated towards hydrogen (H 2). Chemical oxidative polymerization of aniline was employed to synthesize polyaniline nanofibers with WO 3 nanoparticles. The nanocomposite was deposited onto a layered ZnO/64 ° YX LiNbO 3 SAW transducer. The sensor was exposed to various concentrations of H 2 gas and operated at room temperature. The sensor response was found to be 7 kHz towards 1% of H 2 in synthetic air. A fast response and recovery with good repeatability in a stable baseline condition were observed at room temperature.
