Influence of MnC_2O_4 Microadditives on Combustion Characteristics of CuO/Al Nanoenergetics

摘要

In this work, we have investigated the catalytic effect of MnC_2O_4 microrods on combustion characteristics of CuO/nAl nanoenergetic composites. CuO nanorods were prepared by solid state synthesis method using the nonionic surfactant of poly(ethylene)glycol of molecular weight 400 (PEG400). The crystal information and micro structure of CuO/nAl nanoenergetics were studied by X-ray diffractometry and Transmission Electron microscopy. Microrods shaped manganese oxalate (MnC_2O_4) were fabricated by using mild thermal precipitation and aging process and confirmed by energy dispersive X-ray spectroscopy (EDS). The microstructures of MnC_2O_4 microrods and the nanoenergetic composites of CuO/nAl/MnC_2O_4 were characterized by Field emission scanning electron microscopy (FE-SEM) imaging. The addition of MnC_2O_4 microrods has demonstrated a significant enhancement in dynamic pressure-time characteristics of CuO/nAl nanoenergetics.
