In order to improve the safety properties of molecular perovskite energetic materials, ammonium perchlorate-based molecular perovskite ((H2DABCO)[NH4(ClO4)3], DAP)/graphene composite was prepared and characterized. Molecular perovskite DAP was prepared via a molecular assembly strategy by the facile one-pot reaction of triethylenediamine (TEDA, DABCO), perchloric acid, and ammonium perchlorate, and the DAP/graphene composite was fabricated by mechanical mixing with 10 wt.% graphene. The results demonstrated that impact sensitivity (>120 cm), friction sensitivity (25%) and electrostatic spark sensitivity (7.04 J) of the DAP/graphene composite was less sensitive than raw DAP (impact, friction and electrostatic spark sensitivity: 112.3 cm, 45%, and 5.39 J, respectively), due to the composite desensitization mechanism of graphene. This work may offer new ideas for the design and fabrication of insensitive molecular perovskite-based energetic composites.
