Characterization of Al/CuO nanoenergetic multilayer films integrated with semiconductor bridge for initiator applications

“…11 The modulation period of Al/CuO nEMFs is very important parameter, which has a great influence on stoichiometric reaction. In order to affirm a better modulation period, a series of differential scanning calorimetry (DSC) experiments of modulation period have been done, and the results show that Al/CuO nEMFs possess the larger reaction heat (approximately 2181 J/g) when the modulation period is Al(30 nm)/CuO(45 nm).…”

“…9,10 At the same time, our team reported their potential application prospects in energetic initiators. [11][12][13] Semiconductor bridge (SCB) was conceived and patented by Sandia National Laboratories in eighties of last century, which has been very mature in techniques and applications after decades of research and development. [14][15][16][17] Beson and co-works from Sandia National Laboratories described SCB processing and experiments evaluating SCB operation in detail.…”

Self-propagating combustion of sputter-deposited Al/CuO nanolaminates

“…In particular, DC magnetron-sputtering has developed rapidly over the last decade to become a standard manufacturing process for Al/CuO nanothermites; its relatively low cost and easy application to the fabrication of large-area films make it possible to envision the transfer into industrial products. This specific Al/CuO system is widely used for in micro initiation or exploding foil initiators [8][9][10][11] because of its high volumetric energy density (> 13 kJ/cm 3 ) and its propensity to produce hot gas.…”

Electrophoretic deposition and mechanistic studies of nano-Al/CuO thermites

“…One such technique is arrested reactive milling, [17][18][19][20][21][22] which starts with large particles and mills them down until uniform nanoscale mixing is achieved. A second technique involves sputter deposition, [23][24][25][26][27] and has been used to create nanoscale multilayered geometries with controlled precision. An attractive feature of both techniques is that near full-densities can be achieved, which is much more difficult in particle-based composites due to particle-packing considerations.…”
