Abstract
Currently, various groups of scientists are investigating the possibility of using nanostructured porous silicon as promising solid fuels (or additives to composite solid fuels) and as miniature energy sources for microelectromechanical systems. The results presented in the paper demonstrate the prospects of the proposed novations aimed at increasing the efficiency of nanoporous silicon as an energetic material. They are based on the use of mounds of porous silicon fragments treated with sodium perchlorate solutions and dried under low warming (MPSF-composites) as energy composites. For example, when the weights of the MPSF-composites and the porous layer composites on monocrystal substrates treated with sodium perchlorate solutions (PS-composites) are close to each other, the overpressure at the front of the shock waves developing at the initiation and propagation of combustion in the case of MPSF-composites is 5-6 times higher.
