含能材料的性能与其分子结构密切相关，共晶炸药对调控炸药性能具有潜在的优势，并逐步成为含能材料领域里的研究热点。然而，目前共晶炸药的合成尚缺乏科学理论指导，合成效率低。我们在前期研究中发现采用溶剂挥发法合成共晶炸药，周期长，重复性差，难于放大，严重制约共晶炸药的性能评估与应用发展。本项目拟以CL-20和TNB为典型代表，考察共晶各纯组分的溶解特性和相变特征，探明各组分的相转变规律，建立共晶相图，为共晶炸药合成提供理论指导。基于相图开展匹配的共晶炸药合成研究，为共晶炸药的高效合成提供一种普适性方法。另外，考察CL-20/TNB共晶炸药的理化、安全和爆轰性能，探索共晶组分与结构对性能的影响规律，为解决含能材料能量与安全性间矛盾提供必要的科学依据和技术支撑。本研究将有助于揭示共晶炸药形成机制，为共晶炸药的高效合成及其实际应用奠定理论和技术基础，对促进我国共晶炸药可持续研究具有重要科学意义。

The properties of energetic materials depend on its structure,cocrystal explosive has the ability to tune properties of explosives and becomes an interesting focus in energetic materials field. However, nowadays the method to prepare cocrystal explosive has a low efficiency due to lack of theoretical guidance. In our experiment, solvent evaporation requires a long time with difficult in scaling up, limiting the development and application for cocrystal explosives. The phase solubility and phase transition characteristics of pure components will be investigated to obtain the rule of phase transformation for establishing phase diagram in order to provide theoretical guidance for an effective preparation cocrystal explosives. Based on phase diagram, the preparation method also will be developed for offering a high efficient method to prepare cocrystal explosives.Moreover, the properties of cocrystal explosives including physicochemical performance, safety and detonation will be characterized to explore the relation among the components, structures and properties.The main purpose of this project is to reveal the mechanism of cocrystal explosive formation, and provide the theoretical and technical guidance for effective preparation and actual application, promoting the sustainable development of cocrystal explosives.
