基于铝基含能配合物及CL-20含能微芯片的制备及表征

To enhance the energy characteristics and combustion performance of energetic microchips for their application in micro-propulsors, micro-actuators, and micro-detonators, the ECP@AI@ CL-20 energetic array were synthesized through in situ growth of energetic coordination polymer(ECP) on copper foil, e-beam deposition of n-AI, and recrystallization of CL-20. The morphology, phase composition, thermal decomposition, combustion performance, and storage life were characterized by SEM, XRD, TG-DSC and high-speed photography. In addition, the functional ECP@AI@CL-20 energetic microchips were integrated with microelectro mechanical system(MEMS) and subjected to capacitor ignition tests. The results show that the ECP @AI@ CL-20 energetic array reduces heat transfer efficiency from outside to inside due to the low thermal conductivity of ECP, resulting an increase of 8. 5 °C in the exothermic peak temperature compared to pure CL-20, thereby increasing the thermal stability of ECP@AI@CL-20. The ECP@AI@CL-20 energetic array has excellent combustion performance, its self-sustaining combustion time (340 ms) is much higher than that of ECP@AI (120 ms), and it can be ignited under 15 mJ of input energy.
