A gas sensor was developed by depositing polythiophene nanofibers on the surface of ZnO/36° YX LiTaO3 layered
surface acoustic wave (SAW) transducer and tested towards different concentrations of hydrogen gas in synthetic air.
Polythiophene nanofibers were synthesized by using a template-free method through the introduction of an initiator into
the reaction mixture of a rapidly mixed reaction between the monomer (thiophene) and the oxidant. The yield of the
reaction was characterized using scanning electron microscopy (SEM) as well as Ultraviolet-visible (UV-vis) and
Fourier Transform Infrared (FTIR) spectroscopies. The frequency shift due to the sensor response was ~17 kHz towards
1% of H2. All tests were conducted at room temperature. The sensor performance was assessed over a two day period
and a high degree of repeatability was obtained.
