摘　　要：针对常用薄膜换能元的沉积和成型方法耗时长、成本高、材料利用率低等问题,采用喷墨打印制备了银膜换能元,并采用扫描电镜(SEM)和原子力学显微镜(AFM)对换能元形貌及厚度进行了表征,对银膜桥的发火性能进行了研究。结果表明,银膜换能元厚度为2.1μm,表面平整,在不同输入能量下存在电热、电爆两种情况。银膜桥更容易产生等离子体;蘸有斯蒂芬酸铅(LTNR)的银膜桥在47μF脉冲放电下50%发火电压为6.65 V,脚-脚间可以耐受25 kV静电放电(放电电容为500 pF,串联5 kΩ电阻),可通过钝感电火工品1A1W5min测试。In order to solve the problems of long time consumption,high cost and low material utilization in the deposition and forming methods of commonly used thin-film energy conversion component,silver film bridge were prepared by inkjet printing.The morphology and thickness of the silver film bridge were test by scanning electron microscopy(SEM)and atomic mechanics microscopy(AFM),and the ignition performance was studied.The results show that the thickness of the silver film bridge is 2.1μm,and the surface roughness is good.The performance test results show that the silver film bridge has two situations of electric heating and electric explosion under different input energy.Under 47μF pulse discharge,the 50%ignition voltage of the silver film bridge dipped with lead stiphenate(LTNR)is 6.65 V.and the foot-to-foot can withstand 25 kV electrostatic discharge(discharge capacitance is 500 pF,5 kΩresistor in series),which can pass the 1A1W5min test of insensitive electric initiating device.
