Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/polyvinylpyrrolidone (PEDOT:PSS/PVP) composite nanofibers were successfully fabricated via electrospinning and used as a quartz crystal microbalance (QCM) sensor for detecting CO gas. The electrical property of individual PEDOT:PSS/PVP nanofibers was characterized and the room temperature resistivity was at the magnitude of 105 Ω·m. The QCM sensor based on PEDOT:PSS/PVP nanofibers was sensitive to low concentration (5–50 ppm) CO. In the range of 5–50 ppm CO, the relationship between the response of PEDOT:PSS nanofibers and the CO concentration was linear. Nevertheless, when the concentration exceeded 50 ppm, the adsorption of the nanofiber membrane for CO gas reached saturation and the resonant frequency range had no change. Therefore, the results open an approach to create electrospun PEDOT:PSS/PVP for gas sensing applications.

The frequency response of quartz crystal microbalance loaded by single-drop liquid is studied in this paper. Previous studies have shown that the relationship between resonant frequency and properties of liquid by completely immersing one side of the crystal in liquid. In this work, only localized portion of crystal was wetted by liquid droplet. Repeated experiment shows the relationship between liquid property include viscosity and density to resonant frequency. Furthermore, Theoretical formula describing the frequency change of the quartz crystal microbalance with liquid property is proposed. The predicted results showed distinct coincide with experimental results.
