Title: Exploration of Processing Parameters of Vacuum Assisted Micelle Confinement Synthesis of Spherical CL-20 Microparticles

Abstract

We recently developed a vacuum assisted micelle confinement synthesis for spherical microparticles of CL-20 with outstanding monodispersity. These microparticles are promising energetic material for explosive devices with enhanced and predictable performances. In this paper, to facilitate further development and application of this synthesis, the particle growth process was monitored by in-situ dynamic light scattering measurements. The result was interpreted by a finite element model to obtain critical parameters. Finally, these parameters were then used to predict the behavior and product quality of batch synthesis under various operation conditions.
