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… CONTINUE READING
