CL-20/CAB energetic composite microspheres prepared by premix membrane emulsification

Premix membrane emulsification is a quick and efficient method to prepare emulsion. Pre-emulsion was prepared by dissolving 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) and cellulose acetate butyrate (CAB) in ethyl acetate, and the mixture was added to an aqueous solution conta...

description Premix membrane emulsification is a quick and efficient method to prepare emulsion. Pre-emulsion was prepared by dissolving 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) and cellulose acetate butyrate (CAB) in ethyl acetate, and the mixture was added to an aqueous solution containing a surfactant. Then, the droplet uniform emulsion through the transmembrane was formed. The composites with the core–shell structure were obtained after evaporating the solvent. The results displayed that the morphological structure of CL-20 based composite could change from the dumbbell-shaped structure to spherical structure with an increase in the CAB content. Based on the impact sensitivity and thermal properties, the composite enhanced the safety. Meanwhile, a remarkable enhancement in the decomposition peak temperature (Tp0) and the critical temperature of the explosion (Tb) at a relatively low content of CAB (3 wt. %, 5 wt. % and 10 wt. %) was also noted. This approach provides a faster way for the design and preparation of polymer composites.
