Shock wave as a source of energy to influence on nanomaterials

Abstract

Shock wave energy has found multidisciplinary applications in the field of constructive as well as destructive engineering. In material science applications, it is used to study phase transition and mechanical properties of material, synthesis, powder compaction, shock welding etc., In this present work, an attempt has been made to use shock wave as a source of energy to synthesis silica nanoparticles. In general, the processing time of silica is comparatively very high. In order to reduce the processing time, the alternative source of energy in the form of shock waves are impinged on precursor and initiate the reaction in the precursor and also it is used to sustain and control the reactions of nanoparticles. Using Fourier Transform Infrared Spectroscopy (FTIR) the formation of silica nanoparticles are confirmed. Using Field Emission Scanning Electron Microscope (FESEM) the growth of polymerization of silica nanoparticles are observed to be considerably progressed after 20 shocks. The polymerization process of silica nanoparticles take a lead time of approximately 3 hours, by the application of shock wave energy the lead time is reduced to approximately 15 minutes.
