摘要：近年来，随着各种恐怖活动的增加，尤其是爆炸性破坏呈现增多趋势。利用具有荧光特性的纳米纤维对爆炸物进行检测，对有效预防和打击恐怖犯罪活动具有重要意义。本课题通过高压静电纺丝技术制备了系列TPE-PVDF的荧光纳米纤维膜，采用扫描电子显微镜(SEM) 和荧光光谱仪分别对其形貌和光学性能进行表征。此外，在该纤维膜中滴加不同浓度的苦味酸 (PA) 溶液，并对其荧光性能进行测试，获得最低检测极限为1μg/cm3。

Abstract: In recent years, the increasing of various terrorist activities shows a raising trend of explosive destruction. In this study, application of explosive detection, based on fluorescent nanofibers, is very important in term of effective prevention and combating of terrorist and criminal activities. TPE-PVDF nanofiber containing tetraphenylethene compound via electro spinning is fabricated and characterized by scanning electron microscopy (SEM) and fluorescence spectroscopy on its morphology and fluorescent properties, respectively. Furthermore, Picric acid (PA) at variant concentrations is added on the fibrous membrane and tested, with result shows high sensitivity as low as 1 μg/cm3.
