SUMMARY:

The explosives and post blast residues identification is very important for criminal investigations because it provides more safety to professionals and robusts evidences. In this work a fluorescent film was synthesized to detect nitroaromatics explosives traces and the film was synthesized by electrospinning to get a sensitive fiber for explosives. The nanofiber´s structural and morpholigical characteristics were evaluated and related to the sensitivity of the film to determine the synthesis parameters and the suitable morphology for detection. The results for the explosive detection were evaluated and the synthesized film was sensitive to TNT and exhibited fluorescence extinction seconds after the exposure of the film for this explosive under ultraviolet light.
