Reactive antistatic additive modified copper(II) azide as a primary explosive with simultaneously enhanced stability and energy

The emergence of micro-priming systems expedites the demand for balancing the inherent contradiction between energy and safety in primary explosives. This paper proposes a new strategy (metal organic framework/reactive antistatic agent strategy, MOF/RAA strategy) which introduces the reactive antistatic agent (WO3) into ternary copper azide /carbon activity system by carbonization and azide of polyoxometalate-based metal–organic frameworks. Subsequent characterization validates that the novel reactive multi-component system (ternary copper azide /carbon/tungsten trioxide) performs well with both high electrostatic safety and remarkable detonating ability (detonate CL-20 as low as 0.98 mg) due to the electrical conductivity and active participation in secondary reaction of reactive antistatic agent (WO3). In general, this discovery has obtained prominent achievements in the application of copper azide in micro-initiating systems, providing a safe yet energy simultaneously enhanced way for the design and synthesis of novel energetic compounds.
