摘要：

Presented is the structural and gas sensing properties of polyaniline nanofibers deposited on 36 degrees lithium tantalate (LiTaO3) surface acoustic wave (SAW) transducers. The polyaniline nanofibers were synthesized using electropolymerization and subsequently dedoping technique. Field emission scanning electron microscopy (FE-SEM) revealed that the diameter of the polyaniline nanofibers is in the range of 40-50 nm. The SAW sensors with different thicknesses of thin film made of polyaniline nanofibers; were then exposed to different concentrations of hydrogen (H-2) gas at room temperature. (C) 2009 Elsevier B.V.
