TITLE:

Detection of Explosives with the Use of Electro-Spun Fluorescent Films

KEY WORDS:

conductive polymers, fluorescent films, explosives, photoinduced electron transfer.

PAGES: 35
BIG AREA: Ciências Exatas e da Terra
AREA: Química
SUMMARY:

In this work, a fluorescent film capable of detecting traces of explosives was synthesized. The film was synthesized by electrospinning with different voltages to evaluate the best conditions for the synthesis of a fiber more sensitive to the detection of explosive. The thickness of the nanofiber was evaluated and related to the sensitivity of the film in order to determine the best thickness and morphology for detection. The results for the detection of the explosive were evaluated and the synthesized film was sensitive to TNT, showing a fluorescence queenching seconds after the exposure of the film to that explosive when submitted to ultraviolet light.
