Improving DMMP (Salin simulant) sensing characteristics of TFQ functionalized graphene chemiresistive sensors

In order to detect DMMP (dimethyl methyl-phosphonate; sarin simulant), tetrafluorohydroquinone (TFQ) functionalized graphene chemiresistive sensors are successfully developed. The graphene sensors show significantly enhanced sensitivity with various DMMP concentrations. In addition, for the real-time DMMP detection, a method using the first derivative of current sensitivity will be presented.
