To enhance the energy characteristics and combustion performance of energetic microchips for their application in micro-propulsors,micro-actuators,and micro-detonators,the ECP@Al@CL-20 energetic array were synthesized through in si-tu growth of energetic coordination polymer(ECP)on copper foil,e-beam deposition of n-Al,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@Al@CL-20 energetic microchips were in-tegrated with microelectro mechanical system(MEMS)and subjected to capacitor ignition tests.The results show that the ECP@Al@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 ℃ in the exothermic peak temperature compared to pure CL-20,thereby increasing the thermal sta-bility of ECP@Al@CL-20.The ECP@Al@CL-20 energetic array has excellent combustion performance,its self-sustaining combustion time(340ms)is much higher than that of ECP@Al(120ms),and it can be ignited under 15mJ of input energy.
