The detection techniques for traces of energetic materials (EMs) is achieved using fact interaction between fluorescent polymers and EMs. Researchers have designed various fluorophores for explosives detection worldwide. In present study, PAni, DBSA doped PAni (D-PAni), γ-Fe₂O₃PAni composite (Fe-PAni), were synthesized and collectively used terminology as modified PAnis. This were employed for trace detection of EMs like TNT, RDX, PETN, and HNIW/CL-20 and compared outcome with our earlier results of doped PAnis. All the synthesized PAnis were characterized by FT-IR, X-ray diffraction (XRD) and resonance Raman studies, UV–Visible, and photoluminescence (PL). The PL studies showed that quenching is selective and sensitive at ppm level (LOD about 0.04–1.50 μ mL⁻¹) and Fe-PAni emerged as a potential sensor (LOD; 0.092 ± 0.07 μ mL⁻¹). The formation of polaron from bipolaron, the existence of exciton and intermolecular interactions were confirmed and evaluated from the spectrochemical studies.

通过聚苯胺及其不同改性形式检测含能材料

痕量高能材料 (EM) 的检测技术是利用荧光聚合物和 EM 之间的事实相互作用来实现的。研究人员设计了各种用于爆炸物检测的荧光团。在本研究中，合成了 PAni、DBSA 掺杂的 PAni (D-PAni)、γ -Fe ₂ O ₃ PAni 复合材料 (Fe-PAni) 并统称为改性 PAni。这被用于 TNT、RDX、PETN 和 HNIW/CL-20 等 EM 的痕量检测，并将结果与​​我们早期掺杂 PAnis 的结果进行比较。所有合成的 PAnis 均通过 FT-IR、X 射线衍射 (XRD) 和共振拉曼研究、紫外-可见光和光致发光 (PL) 进行表征。PL 研究表明，猝灭在 ppm 级（LOD 约 0.04–1.50 μ mL^-1 ) 和 Fe-PAni 作为电位传感器出现 (LOD; 0.092 ± 0.07 μ mL ^-1 )。双极化子形成极化子，激子的存在和分子间相互作用从光谱化学研究中得到证实和评估。
