Novel Approach to the Preparation of Organic Energetic Film for Microelectromechanical Systems and Microactuator Applications

Abstract

An activated RDX-Fe2O3 xerogel in a Si-microchannel plate (MCP) has been successfully prepared by a novel propylene epoxide-mediated sol-gel method. A decrease of nearly 40 °C in decomposition temperature has been observed compared with the original cyclotrimethylene trinitramine (RDX). The RDX-Fe2O3 xerogel can release gas and solid matter simultaneously, and the ratio of gas to solid can be tailored easily by changing the initial proportions of RDX and FeCl3·6H2O, which significantly enhances the explosive and propulsion effects and is of great benefit to the applications. The approach, which is simple, safe, and fully compatible with MEMS technology, opens a new route to the introduction of organic energetic materials to a silicon substrate.

Enhanced thermopower wave via nanowire bonding and grain boundary fusion in combustion of fuel/CuO–Cu2O–Cu hybrid composites

“…5 Some examples of such applications include microthrusters, 6 nanothermites, 7 and microactuators. 8 In many cases, the energy conversion in micro/ nanostructures occurs as a result of the interplay between nonconventional and conventional energy sources. For example, energy harvesting, waste heat and fuel recoveries in combustion, solid materials synthesis, and combustion synthesis inevitably involve simultaneous chemical-thermal-electrical energy conversions.…”

Progress in Additive Manufacturing of Energetic Materials: Creating the Reactive Microstructures with High Potential of Applications

“…Figure 1 illustrates a wide set of techniques suited for RMS fabrication. Note that we focus on the fabrication of objects with a certain degree of structural integrity; therefore, technologies elaborated for the production of powdered samples, e. g., arrested reactive milling [37], spray drying [38], and sol-gel synthesis [39,40], fall outside of the scope of the review.…”

Simultaneously Altering the Energy Release and Promoting the Adhesive Force of an Electrophoretic Energetic Film with a Fluoropolymer

“…Thermites, a kind of composite energetic material (EM) consisting of solid metal fuel and oxidizer particles, have been applied in high-energy exchange components, such as electronic packaging, self-propagating welding, and self-propagating high-temperature diffusion welding. , Reactive films as the typical form of thermites, also termed thermite laminates, have attracted a great deal of interest with respect to their compatibility and high energy and power density (superior to those of supercapacitors) . Various applications of reactive coatings have been realized in microelectromechanical systems, microignitor devices, microelectronics, and bonding of materials …”
