Construction of nano-sized FOX-7/ZIF-8 composites for fast decomposition and reduced sensitivity.

Herein, novel nano-sized 1,1-diamino-2,2-dinitroethylene (C 2 H 4 N 4 O 4 , FOX-7)/zeolitic imidazolate framework-8 (ZIF-8) composites are constructed by facile liquid-assisted mechanochemical reactions. In contrast to two-step thermal decomposition of raw FOX-7, the prepared FOX-7/ZIF-8 composites demonstrate a single high-intensity exothermal decomposition attributed to the catalysis of ZIF-8. Benefiting from nano-sized energetic materials and the buffering effect of ZIF-8, the mechanical sensitives of FOX-7/ZIF-8 composites are decreased.
