Building Energetic Material from Novel Salix Leaf-like CuO and Nano-Al through Electrophoretic Deposition

摘要

In this study, an energetic material was prepared by depositing nano-Al on CuO arrays via electrophoretic deposition (EPD), which offers a feasible route for nano-Al integration. The morphology and structure of the CuO arrays and Al/CuO composites were characterized by scanning electron microscopy and X-ray diffraction. The CuO arrays were homogenously salix leaf-like structure with a width of similar to 150 to 200nm. The energy density of Al/CuO composites was approximate to 1454.5J/g by integrating the differential scanning calorimetry (DSC) plot and the combustion performance was recorded by a high-speed camera. Moreover, the combustion flames were violent and the whole reaction process only lasted 72.2ms, indicating that the energy of the Al/CuO nanothermite can be released effectively.
