Thermal behavior and combustion of Al nanoparticles/ MnO-nanorods nanothermites with addition of potassium perchlorate.

To explore the effect of potassium perchlorate (KClO) on Al nanoparticles/MnO-nanorods nanothermite systems, in this paper, Al/MnO nanothermites with different mass fraction of KClO were prepared by electrospray. The samples were characterized by XRD, SEM, TG-DSC analysis. According to the results of TG-DSC, the addition of KClO seemed to cause no direct improvement on their exothermic reactions.

Study on thermal behavior and kinetics of Al/MnO poly(vinylidene fluorine) energetic nanocomposite assembled by electrospray.

To explore the effect of the addition of poly(vinylidene fluorine) (PVDF) to a nanothermite system, an Al/MnO/PVDF energetic nanocomposite was prepared using an electrospray method, Al/MnO nanothermite was prepared as a control group. Then, the energetic nanocomposite and nanothermite were tested and analyzed by XRD, FE-SEM and TG-DSC, and the reaction products were collected. The results show that energetic nanocomposite would have three obvious exothermic peaks in the range of room temperature to 800 °C with a total more than 1700 J g heat release while the control experiment, Al/MnO nanothermite, could be found one exothermic peak with a 1100 J g heat release.
