Graphene oxide microsensors for 2,4-Dinitrotoluene detection
Research in the field of explosives detection due to the increased use of these materials in terrorist attacks is growing. In this paper, a chemiresistor gas sensor based on Graphene oxide functionalized with 2,2,3,3,4,4,5,5-Octafluoro-1,6-hexanediol is provided and its response to 2,4-Dinitrotoluene is studied. response of the sensor by adding the second coating layer on the functionalized graphene oxide show considerable increase the sensitivity and selectivity of the sensor .Linear response range for DNT, 91.8-918 ppb with a detection limit 76 ppb is obtained. Also the RSD to evaluate the repeatability of sensor for 3 replicate measurements was 6.09%.
