We report a chemiresistor that has been fabricated via simple spin-casting technique from stable CNT dispersion in hexafluoroisopropanol functionalized polythiophene. The sensor has shown high sensitivity and selectivity for a nerve reagent stimulant DMMP. A series of sensing studies, including field effect investigation, electrode passivation, and fluorescent measurement, indicate a combinative mechanism of charge transfer, introduction of scattering sites, and a configurational change of the polymer.
我们报道了一种通过简单的旋涂技术由稳定的碳纳米管分散体在六氟异丙醇官能化聚噻吩中制备的化学电阻器。该传感器对神经试剂刺激物二甲基甲基膦酸酯（DMMP）表现出高灵敏度和选择性。一系列传感研究，包括场效应研究、电极钝化和荧光测量，表明了电荷转移、散射位点引入和聚合物构型变化的组合机制。
