英文摘要： A novel method for designing micro-structured energetic device is presented to solve the problems of low output energy and complicated fabrication process about the micro initiators. The investigation will be concentrated on in-situ synthesis technology of nano-azide copper and integrated manufacturing technology of micro-structured energetic devices. Nano-copper meshes will be fabricated by electrochemical method, whose characteristics of extremely high specific surface area and reactivity contribute to control the in-situ synthesis of the high energy density and low limit initiation explosive and eliminate the potential hazard in the traditional charge condition. The samples will be characterized by SEM, TEM, BET, DSC and TG-DTA. The in-situ synthesis mechanism will be investigated to construct the azide reaction model of nano-copper mesh. In order to solve the problem of ignition ability for small bridge membrane, Al/CuO/Al reactive composite bridge membrane will be fabricated by film deposition and photolithography to investigate the electrical explosion characteristics. A novel integration method for micro-explosive array and energetic device has been explored by analyzing the integration and packaging process of MEMS. This research has potential application for the fuze security setup and attitude control
