New energetic composites with enhanced reactive performances while allowing the safe handling according to their sensitivity thresholds are presented. This paper combines different approaches: the intimate contact between the compounds, the particle size reduction and the processing of composite materials to maintain the oxygen balance close to zero. The Spray Flash Evaporation process enables the fast crystallization at the submicron scale by combining an oxidizer, ammonium dinitramide ADN and two secondary explosives (RDX and HMX). The morphologies of the particles were analyzed and compared with slow evaporation tests. An intimate mixing between the two components (crystallized by SFE) is highlighted and core‐shell structure is evidenced by advanced techniques such as 2D and 3D confocal Raman microscopy. The composites offer outstanding energetic performances compared to sole explosives. It paves the way to new energetic compositions based on current materials.

调整高能复合材料的氧平衡：通过喷雾蒸发蒸发ADN /第二炸药混合物的结晶

提出了具有增强的反应性能同时允许根据其灵敏度阈值进行安全处理的新型高能复合材料。本文结合了不同的方法：化合物之间的紧密接触，减小粒径以及处理复合材料以保持氧平衡接近于零。通过将氧化剂，二硝酰胺铵ADN和两种辅助炸药（RDX和HMX）结合使用，喷雾快速蒸发工艺可实现亚微米级的快速结晶。分析了颗粒的形态，并与慢速蒸发测试进行了比较。突出显示了两种成分之间的紧密混合（通过SFE结晶），并通过2D和3D共焦拉曼显微镜等先进技术证明了核壳结构。与单独的炸药相比，该复合材料具有出色的能量性能。它为基于当前材料的新的高能成分铺平了道路。
