Polypyrrole material for the electrostatic discharge sensitivity mitigation of Al/SnO ₂ energetic composites

Nanothermites are composite energetic materials made of fuel and oxidizer nanoparticles characterized by impressive exothermic reactions (highly flame temperatures heat combustion releases). However, nanothermites suffer from their high electrostatic discharge (ESD) sensitivity that may be at the origin accidental ignitions during handling. The present study deals with use doped-polypyrrole conducting polymer in aluminum/tin (IV) oxide formulation (Al/SnO2). X-ray diffraction, Fourier transforms infrared spectroscopy, scanning electron microscopy, conductivity measurements, sensitivities tests were implemented to characterize polypyrrole-doped Al/SnO2 composite. results revealed a significant gradual ESD desensitization nanothermite (<0.14 mJ 246.40 mJ) as function amount (0 15 wt%). reactive properties polypyrrole-enriched verified an acceptable behavior was claimed. successful adding within nanocomposites is reported for first time.
