The work, which shows that using electrospray deposition fabricates the spherical particles consisting of n-Al and reactive binder, expects an approach to the promising n-Al in energetic materials. The burning duration decreases from 3.51 s to 219 ms as the PVDF concentration increases. The combustion properties tested in open air show that all samples can be ignited, while the n-Al/PVDF demonstrated more active reactivity in comparison with n-Al. Thermogravimetric–differential scanning calorimetric analysis shows more intense heat release process (the sharper exothermic peak) compared to n-Al. In this study, nanoaluminum (n-Al)/PVDF microsphere particles with diameters of between 1 and 5 μm were successfully prepared with PVDF content of 5, 10 and 15 % by mass using the electrospray deposition method. The strong electronegative fluorine within the polymer can react with the alumina passivation shell surrounding an aluminum (Al) particle to promote Al particle reactivity. Polyvinylidene fluoride (PVDF) is a potential oxidizer for aluminum powders as well as an excellent binder.
