摘　　要：针对定向碳纳米管迚行了制备和填充,得到了核壳结极的碳纳米管复合含能材料。为了探究氧化物KNO3在管内和管外负载的区别,采用激光点火实验对KNO3+CNTs和KNO3@CNTs("+"代表硝酸钾与碳纳米管研磨混合,"@"代表硝酸钾填充在碳纳米管管内)这2种定向碳纳米管复合药剂迚行激光点火性能表征。结果表明,与KNO3+CNTs相比,KNO3@CNTs材料的激光点火延迟时间和激光点火能量更小,节约了点火输入能量,提高了能量利用率。Aligned carbon nanotubes(CNTs) were prepared and filled with nitrate oxidant in this dissertation. The laser ignition properties of two aligned carbon nanotubes reagent KNO3+CNTs and KNO3@CNTs(’+’ expresses tube external composite, ’@’expresses tube internal composite) were investigated. The results show that the laser ignition delay time and laser ignition energy of KNO3@CNTs are less than that of KNO3+CNTs. KNO3@CNTs can save ignition input energy and improve energy utilization.
