Nitroaromatic explosives are the most common explosives, and their detection is important to public security, human health, and environmental protection. In particular, the detection of solid explosives through directly revealing the presence of their vapors in air would be desirable for compact and portable devices. In this study, amino-functionalized carbon nanotubes were used to produce resistive sensors to detect nitroaromatic explosives by interaction with their vapors. Devices formed by carbon nanotube networks working at room temperature revealed trinitrotoluene, one of the most common nitroaromatic explosives, and di-nitrotoluene-saturated vapors, with reaction and recovery times of a few and tens of seconds, respectively. This type of resistive device is particularly simple and may be easily combined with low-power electronics for preparing portable devices.
硝基芳香族炸药是最常见的炸药，其检测对公共安全、人类健康和环境保护至关重要。特别是，通过直接检测空气中其蒸汽的存在来检测固体炸药，对于紧凑便携的设备来说是很有必要的。在本研究中，氨基功能化碳纳米管被用于制造电阻式传感器，通过与硝基芳香族炸药蒸汽相互作用来检测它们。由碳纳米管网络组成的器件在室温下工作，能够检测到最常见的硝基芳香族炸药之一三硝基甲苯以及二硝基甲苯饱和蒸汽，反应时间和恢复时间分别为几秒和几十秒。这种类型的电阻式器件特别简单，并且可以很容易地与低功耗电子设备结合以制备便携式设备。
