▎ 摘  要

NOVELTY - Preparing graphitic carbon nitride (g-C3N4) based composite energetic material, comprises grinding g-C3N4 and explosive by adopting physical grinding, in-situ reduction and electrostatic self-assembly method to obtain a composite material I, coating the g-C3N4 and graphene oxide (GO) on the surface of the explosive crystal to obtain a composite material II, utilizing the high cation characteristic of polyethyleneimine to modify the surface of ammonium nitrate explosive and obtain a composite material III by electrostatic self-assembling method. USE - The method is useful for preparing g-C3N4 based composite energetic material. ADVANTAGE - The method combines g-C3N4 and GO to reduce the sensitivity of ammonium nitrate explosive crystal and obtain the composite material with reducing and high energy performance, and utilizes high stability, high thermal conductivity and lubricity of g-C3N4 and GO to passivate the mechanical sensitivity of the energetic material.
