详细技术说明

To create these energetic materials and thin film explosives, layered MIC deposition is accomplished through the contact of two different solid reactants, such as copper oxide and aluminum, which releases heat, resulting in a self-propagating reaction. This is done by sputtering in a vacuum chamber at a low pressure, helping in the reduction of water vapor content. Additionally, pure chemical inert gas is used for sputtering to provide higher purity and prevent water vapor contamination. Moreover, the thickness of the interfacial region over the entire surface area of reactants is less than 2 nanometers, providing higher reaction velocity.

*Abstract

This technology from the University of Central Florida reduces the presence of water vapor by nearly a hundred times, which allows for much thinner interfacial regions between the nanolayers, a higher stored energy density, and a reaction velocity that is five times faster than conventional designs. In addition, the controlled application of intense amounts of heat through regulated rapid heat release improves welding, soldering, and brazing, without damaging the peripheral materials.
