The development of sensitive materials for standard and improvised explosives is greatly significant to homeland security. In this paper, the phosphotungstate (NaPT) doped polyphenylene vinylene (PPV) nanotube arrays (NTAs), with excellent optical response, chemical stability, and larger specific surface area, are successfully fabricated by means of the “precursor film” infiltration method. The efficient charge carriers' separation of PPV NTAs can be achieved by doping NaPT to realize the photoelectric detection of explosive vapors. In addition, the identification of six explosives, including ammonium nitrate (AN), dinitrotoluence (DNT), picric acid (PA), p-nitrotoluene (PNT), triacetone triperoxide (TATP), and trinitrotoluene (TNT), can also be realized through the fingerprint atlas. Moreover, the adsorption energy and excited oscillator intensity has also been employed to explain the interaction between NaPT doped PPV nanotube arrays and various explosive molecules. Obviously, the NaPT doped PPV developed has the potential to be used as an explosive sensor.

用于通过激发波长调节进行爆炸物识别的 PPV 纳米管传感器阵列
开发用于标准和简易炸药的敏感材料对国土安全具有重要意义。在本文中，磷钨酸盐（NaPT）掺杂的聚苯撑乙烯（PPV）纳米管阵列（NTA）具有优异的光学响应、化学稳定性和更大的比表面积，通过“前体膜”渗透方法成功制备。通过掺杂NaPT实现对PPV NTAs的高效电荷载流子分离，实现爆炸性蒸气的光电检测。此外，还可实现硝酸铵（AN）、二硝基甲苯（DNT）、苦味酸（PA）、对硝基甲苯（PNT）、三过氧化三丙酮（TATP）、三硝基甲苯（TNT）六种爆炸物的鉴别通过指纹图谱。而且，吸附能和激发振子强度也被用来解释 NaPT 掺杂的 PPV 纳米管阵列和各种爆炸分子之间的相互作用。显然，开发的 NaPT 掺杂 PPV 具有用作爆炸传感器的潜力。
