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 ~150 to 200 nm. The energy density of Al/ CuO composites was approximate to 1454.5 J/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 72.2 ms, indicating that the energy of the Al/ CuO nanothermite can be released effectively.
