Enhancement of laser ignitibility of insensitive energetic materials (FOX‐7)

Abstract Experimental investigation into the feasibility of optically sensitising an insensitive explosive, FOX‐7 (1,1‐Diamino‐2,2‐dinitroethene) by doping gold nanoparticles (GNPs) has been conducted. The commercially available GNPs were specifically designed in their particle shape and size to strongly absorb at wavelength igniting laser (808 nm). ignitibility was significantly increased as efficiently converted absorbed energy heat. such sensitised detonation capability initiator devices for study evaluated. Based on evaluation initiator's output term impact pressure, it shown that doped based slapper able detonate a secondary explosive.
