Encapsulation of energetic materials by cooling and electrospray crystallization
conference paper
In this work cooling and electrospray crystallization have been used to create encapsulated (sub-)micron sized particles of different crystalline materials. Encapsulation experiments have been conducted, creating the core particle in situ from solution, with the model systems isonicotinamide (INA) – caffeine and RDX – TNT. Concentrations of the compounds in solution were varied in order to control core and shell material. With INA – caffeine encapsulation could be forced in electrospray crystallization, while only limited encapsulation was achieved during cooling crystallization experiments. With RDX – TNT spherical nano-particles could be produced using electrospray crystallization. However the composition of the particles needs further investigation.
