Effects of Carbon Nanotubes on the Sensitivities of Pyrotechnic Compositions

Two kinds of pyrotechnic compositions modified by carbon nano-tubes (CNTs) were prepared in this paper. One is ignition mixture, the other is initial detonating agent, lead styphnate (LTNR). The effects of CNTs distribution in the ignition mixtures on the flame sensitivity were studied. The result showed that the additive of clustered CNTs can increase the flame sensitivity of the mixture. The effects of additive of CNTs in LTNR on several agent sensitivities and caloric decompose property were also studied in this paper. The additive of CNTs can obviously reduce the mechanical and static electric charge sensitivities of LTNR, but the flame sensitivity stays nearly unchanged.
