Abstract:
With the recent implementation of nano sized metal powders into energetic composites such as solid rocket propellants, incorporating metal nanoparticles with high mass loading in the propellant has become an issue. In this work, an electrospray deposition technique was employed to increase particle loading of nano aluminum n-Al and demonstrate the potential of the fluoropolymer, polyvinylidene fluoride PVDF, as an energetic binder. A mass percentage of 50 n-Al in PVDF was determined to have the optimal combustion qualities when ignited in air. The AlPVDF energetic nanocomposite film morphologies were analyzed using scanning electron microscopy SEM and energy-dispersive x-ray spectroscopy EDS. Combustion characteristics of the film were analyzed using thermogravimetric analysismass spectrometry TGAMS and temperature jump time of flight mass spectrometry T-jump TOFMS. Ignition temperatures were determined at various pressured in air and argon environments.
