Enhanced the combustion performances of ammonium perchlorate-based energetic molecular perovskite using functionalized graphene

Abstract Ammonium perchlorate-based molecular perovskite (DAP)/graphene energetic composite was prepared and characterized. Molecule perovskite DAP was synthesized by the one-pot reaction of ammonium perchlorate, perchloric acid, and triethylenediamine, and DAP/graphene energetic composite was fabricated by physical mixing. The results suggested functionalized graphene can contribute to the improvement of combustion properties of DAP effectively. The energetic composite have high sustained exothermic capacity as well as good self-propagating combustion performance. Synergistic catalysis combustion mechanism of the composite system was provided based on relay-domino-like reactions, which enhanced heat and mass transfer between each component and promoted energy release. This work maybe offer a new idea for design and fabrication of high performance graphene-based energetic composite.
