This work describes the first example to demonstrate the enhancement of performances of composite highly energetic materials by mean of employing standard CuO nano-powder as burning rate catalyst in comparison to micro-fillers. The solid composite propellants with CuO microparticles are less stable due to oversensitivity to pressure variations, but the nano-structured composite propellant yields high stable burning rates over a broad pressure range. In addition, the incorporation of CuO nanoparticles in the formulations of these energetic materials also improves their combustion and thermal properties, according to the characterization obtained by differential scanning calorimetry (DSC) and thermogravimetry analysis (TGA). These results indicate the excellent benefits found in using these nanoparticles as additive for solid rocket propulsion applications.
这项工作描述了首个实例，即与微填料相比，通过使用标准氧化铜纳米粉末作为燃速催化剂来提高复合高能材料的性能。含有氧化铜微粒的固体复合推进剂由于对压力变化过于敏感而稳定性较差，但纳米结构复合推进剂在很宽的压力范围内能产生高稳定的燃速。此外，根据差示扫描量热法（DSC）和热重分析（TGA）获得的表征结果，在这些含能材料配方中加入氧化铜纳米颗粒也改善了它们的燃烧和热性能。这些结果表明，将这些纳米颗粒用作固体火箭推进应用的添加剂具有显著优势。
