Abstract

Advanced energetic composites possess promising properties and wide-ranging applications in explosives and propellants. Nonetheless, most metal-based energetic composites present significant challenges due to surface oxidation and low-pressure output. This study introduces a facile in situ method to develop energetic composites Cutztr@AP through the intermolecular assembly of nitrogen-rich energetic coordination polymers and high-energy oxidant ammonium perchlorate (AP). Morphological analysis reveals the unique structure of Cutztr@AP, where Cutztr is distributed throughout the interior and surface of the AP particles. The nonisothermal thermodynamic analysis reveals a heat release of 2378.2 J g-1 for Cutztr@AP2, outperforming the Cutztr/AP2 achieved through ultrasonic mixing (2000 J g-1). Notably, Cutztr@AP2 exhibits promising combustion and pressure output performances, including a significantly shorter duration, a larger flame area, and higher pressure values. This novel and facile preparation technique and microstructure design approach holds significant promise for high-performance propellants, gas generators, and other related applications.

高氯酸铵原位组装3-(四唑-5-基)三唑配合物制备高性能高能复合材料。
先进高能复合材料在炸药和推进剂中具有广阔的应用前景。然而,由于表面氧化和低压输出,大多数金属基高能复合材料面临着重大挑战。本研究介绍了一种简单的原位方法,通过富氮能配位聚合物和高能氧化剂高氯酸铵(AP)的分子间组装来制备含能复合材料Cutztr@AP。形态学分析揭示了Cutztr@AP的独特结构,其中Cutztr分布在AP颗粒的内部和表面。非等温热力学分析表明,Cutztr@AP2的热释放量为2378.2 J - g-1,优于超声混合的Cutztr/AP2 (2000 J - g-1)。值得注意的是,Cutztr@AP2表现出有希望的燃烧和压力输出性能,包括明显更短的持续时间,更大的火焰面积和更高的压力值。这种新颖简便的制备技术和微观结构设计方法在高性能推进剂、气体发生器和其他相关应用中具有重要的前景。
