Synthesis of highly-energetic nanoparticles based on monodisperse hollow mesoporous nanospheres

Highly-energetic monodisperse nanospheres were prepared based on surface-modified, hollow mesoporous silica nanospheres. The monodisperse, cationic polymer nanospheres were prepared by the emulsifier-free emulsion copolymerization and used as a template to obtain copolymer/silica core-shell nanospheres and monodisperse, hollow mesoporous silica (HMS) nanospheres. The surface of the HMS nanospheres was treated with (3-aminopropyl) trimethoxysilane to obtain (3-aminopropyl)trimethoxysilane-grafted HMS nanospheres, which facilitated the adsorption of cyclomethylene trinitramine within the inorganic framework. The uptake of RDX within the dried, final nanospheres was measured by thermogravimetric analysis.
