| 摘 要： | 以聚偏氟乙烯(PVDF)为敏感材料,石英晶体微天平(QCM)为敏感元件构成聚合物QCM传感器。该文主要对神经毒剂模拟剂DMMP的气敏特性进行研究,并重点讨论了温度对PVDF聚合物膜层QCM传感器性能的影响。结果表明,当测试温度愈接近PVDF的玻璃化温度,传感器的响应幅值就愈高,且在各个DMMP测试气氛浓度时,传感器的响应幅值对温度的依赖性均符合Arrhenius关系;升高温度有利于提高传感器的响应速度,但同时其灵敏度却降低。

| Abstract: | 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 ... |
