The afterburning effect of aluminized explosives makes them have strong damage ability to soft targets, but the aluminum particles in the composition often cannot achieve proper combustion. The high ignition temperature of micron aluminum powder is one of the main reasons. In this work, we introduce nanothermite reaction with low onset temperature (<660 °C) into aluminized explosives by replacing the base explosives with energetic coordination polymers (ECPs). The decomposition products of many ECPs contain corresponding metal oxides that will react with aluminum via thermite reaction. Three kinds of ECPs ([CoC₂H₄N₈O₄]_n, [NiC₂H₄N₈O₄]_n and [CuC₂H₄N₈O₄]_n) are constructed and compounded with nano-aluminum (nano-Al) particles to form aluminized ECPs. The influence of metal ion species and Al/Metal (Al/Me) molar ratio on their energetic properties are systematically studied. The results show that the exothermic thermite reaction with low onset temperature plays an important role in the combustion propagation of aluminized ECPs, and the possible mechanism is proposed. When the Al/Me molar ratio is 3–4, the aluminized ECPs have the best peak pressure and pressurization rate. At the optimum molar ratio, the pressure and pressurization rate of aluminized ECP(Co) are much higher than those of aluminized ECP(Ni) and ECP(Cu). Among the three kinds of aluminized ECPs, the aluminized ECP(Co) has the best energetic characteristics and can be used as a preferred choice. However, for the applications that require a long-time heat supply, aluminized ECP(Cu) will be suitable.

由过渡金属中心（Co、Ni 和 Cu）构成的镀铝高能配位聚合物

含铝炸药的后燃效应使它们对软目标具有很强的杀伤能力，但其成分中的铝颗粒往往不能实现适当燃烧。微米铝粉的着火温度高是主要原因之一。在这项工作中，我们通过用高能配位聚合物 (ECP) 代替基础炸药，将低起始温度 (<660 °C) 的纳米铝热反应引入铝化炸药。许多 ECP 的分解产物含有相应的金属氧化物，它们会通过铝热反应与铝反应。三种 ECPs ([CoC ₂ H ₄ N ₈ O ₄ ] _n , [NiC ₂ H ₄ N ₈ O₄ ] _n和 [CuC ₂ H ₄ N ₈ O ₄ ] _n) 由纳米铝 (nano-Al) 颗粒构成并复合以形成镀铝 ECP。系统地研究了金属离子种类和 Al/Metal (Al/Me) 摩尔比对其能量特性的影响。结果表明，低起始温度的放热铝热反应在铝化ECPs的燃烧传播中起重要作用，并提出了可能的机理。当 Al/Me 摩尔比为 3-4 时，镀铝 ECP 具有最佳的峰值压力和加压速率。在最佳摩尔比下，镀铝ECP(Co)的压力和加压速率远高于镀铝ECP(Ni)和ECP(Cu)。在三种镀铝ECPs中，镀铝ECP(Co)具有最好的能量特性，可作为首选。然而，
