PREPARATION AND CHARACTERIZATION OF NANO-POROUS SILICON BASED ENERGETIC MATERIAL

摘要

This work presents an energetic material based on nano-porous silicon fuelimpregnated with an oxidizer. The nano-porous silicon layers were prepared byanodization of silicon in a hydrofluoric acid solution and characterized to study theinfluence of the electric current density on the nano-porous structure properties. Theoxidizer impregnation process was studied thoroughly in order to achieve optimized porefilling by the oxidizer. Feasibility proof for an energetic reaction of nano-porous siliconimpregnated with an oxidizer was demonstrated by thermal analysis using differentialscanning calorimetry.
