Synthesis of energetic material particles with controlled morphology
| DWPI Title: Synthesizing energetic material particles involves providing first solution comprises hexanitrohexaazaisowurtzitane, first solvent, providing second solution includes second solvent that is immiscible |
| Abstract: A surfactant-assisted self-assembly method can be used to crystallize energetic materials with controlled morphology. Microparticles of hexanitrohexaazaisowurtzitane (CL-20) formed by this method may have enhanced functional reproducibility due to their monodisperse nature, and decreased shock sensitivity due to their sub-2 μm particle size. |
| Use: Method for synthesizing energetic material particles. |
| Advantage: The method enables to synthesize energetic material particles that has high volatility, and improves energetic materials. |
| Novelty: Synthesizing energetic material particles involves providing first solution comprises hexanitrohexaazaisowurtzitane, first solvent, providing second solution includes second solvent that is immiscible and has higher boiling point than first solvent. The surfactant is provided in first or second solution. The first and second solutions are mixed to form emulsion which includes first solvent dispersed in second solvent. The first solvent is evaporated to form particles of hexanitrohexaazaisowurtzitane. |
