  • Poly (vinylidene fluoride) (PVDF) modified quartz crystal microbalance (QCM) sensor has been prepared for DMMP vapor detection. The temperature influence on the performances of the sensor was emphatically investigated. The results show that the sensitivity of the sensor is higher with the working temperature closer to the glass transition temperature (Tg) of PVDF, and the absolute frequency responses of the PVDF coated QCM sensor all exhibit negative Arrhenius temperature dependency in spite of different vapor concentrations. In this case, increasing the sensor operating temperature resulted in an improved response time while worse sensor sensitivity was also observed.
