A composite having a substrate and a plurality of core-shell nanoparticles. The substrate has microporosity, nanoporosity, or free volume and is a polymer matrix, a metal-organic framework, a micro-porous structure, or a nano-porous structure. The plurality of core-shell nanoparticles each has a core and at least one shell layer. The core is made from a decomposed product of a first precursor disposed in the microporosity, nanoporosity, or free volume of the substrate. The at least one shell layer is made from a decomposed product of a second precursor and is disposed on the core.

An explosive composition comprising a high density hydrocarbon compound selected from the group consisting of xylitol, sucrose, mannitol, and mixtures thereof and at least one energetic material. The high density hydrocarbon compound and the at least one energetic material form a substantially homogeneous explosive composition. A method of producing an explosive composition that is insensitive to impact is also disclosed.

The invention discloses a preparation method of an ammonia water functionalized graphene insensitive coated energetic material, which comprises the steps of (1) dispersing graphene in a water phase to obtain a graphene dispersion liquid, and adding an energetic material into the graphene dispersion liquid to be continuously dispersed to obtain a first mixed solution, wherein the mass ratio of the energetic material to the graphene is 98: (0.05-1.95); (2) in a stirring state, adding ammonia water into the first mixed solution to obtain a second mixed solution; (3) heating the second mixed solution to the temperature of 60-100 DEG C, and continuously stirring to obtain a suspension; and (4) filtering, washing and drying the suspension to obtain the ammonia water functionalized graphene insensitive energetic material. The method can improve the coating effect and reduce the mechanical sensitivity of the energetic material.

The invention discloses a metal hydride in situ polymerization and cladding passivation method, and is characterized by comprising the following steps: (1) dissolving 3,3-diazido methyloxetane and tetrahydrofuran (BAMO-THF) copolyether and a curing agent into anhydrous ethyl acetate, and preparing into a dilute solution; (2) putting metal hydride into the dilute solution and performing ultrasonic dispersion to form suspension liquid; (3) stirring and warming to the temperature of 40 to 60 DEG C, stirring for reaction, and recycling the solvent ethyl acetate by evaporation after the reaction is ended; (4) a product obtained after the solvent is removed completely by evaporation is dried and cured in a drying oven, so as to obtain the clad passivated metal hydride. According to the metal hydride in situ polymerization and cladding passivation method provided by the invention, the BAMO-THF copolyether is used for in situ polymerization and cladding of the metal hydride, and the treated and obtained metal hydride is insensitive to water in air. The own energy performance of the metal hydride is not affected while passivating the metal hydride.
