AbstractResearch into the energetic reaction of aluminum and TeflonTM nanoparticles was initiated at the Wright Laboratory Armament Directorate. A coating system to improve the handlability of nanosized aluminum powders and a model of the reaction mechanism was requested. The true thermodynamic nature of the reaction was not determined; however, the reaction rate of ~1 km/sec warrants further investigation. TPL's innovation is a material systems which incorporates aluminum nanoparticles passivated by a fluorinated polymer. The thickness of the coating will be alterable by simple procedures to tailor the reaction rate. Other chemical additives will be selected to alter the thermodynamic potential of the system. A physics based model will be developed. Dynamic tests will be performed to evaluate the powder and support model development. A fluorinated surfactant systems will be developed which adsorbs to aluminum nanoparticles. Polymerizable cosurfactants will be added to the system. The durability, oxygen permeability and thickness will be evaluated. A model will be developed to identify a deflagration or detonation reaction mechanism. TPL posses all the elements necessary for successful completion of the Phase I project, including knowledge of the synthesis, powder testing and explosives modeling. Several commercial opportunities for the energetic material have been identified.
