Electrochemical in-situ synthesis of Cu/ICM-101 films for functional energetic chips
Integrating energetic materials with microelectromechanical systems (MEMS) to realize miniaturized energetic chips has shown broad application prospects in micro-spacecraft, micro-satellites, ballistic correction munitions, and smart munitions. In this work, a new type of MEMS compatible Cu/ICM-101 energetic film was successfully fabricated on copper substrates by in-situ electrochemical synthesis, the morphology and ignition property of which can be effectively controlled by adjusting the voltage and electrochemical deposition time. The morphology, composition, thermal properties, and ignition performance of as-prepared Cu/ICM-101 films were characterized by scanning electron microscopy, X-ray diffraction, differential scanning calorimetry, and pulsed laser. The results show that the as-prepared Cu/ICM-101 films possesses nano porous framework structure with an exothermic heat of 1800.9 J·g −1 and a thermal decomposition peak temperature of 256.4 °C. In addition, the flame height and ignition duration of which reach 10 mm and 300 μs, respectively. This work provides a reference for the integration and application of energetic materials in MEMS systems.
