Highly energetic compositions based on functionalized carbon nanomaterials

“…thermites, gas generators and solid-fuel rockets. 272,273 The initiator compositions are similar to those of flash powders but they are different in their burning rate. Although the explosion of igniters is not favored, they are responsible for an intentionally high production of hot particles.…”

“…Commonly used oxidizers are KP and KN, while typical fuels are Ti, titanium(II) hydride, zirconium, zirconium hydride and boron. 274 There are many factors that affect the energy output of these compositions, whose performance can be modified by catalysts or energetic additives. 275 It was found that ignition of BNCP by laser was difficult but the inclusion of just 5 wt% of CNTs or CB significantly decreases both the critical energy for ignition and the ignition delay time.…”

Energetic igniters realized by integrating Al/CuO reactive multilayer films with Cr films

“…15, for instance, high security and reliability. Moreover, the igniter in this work has lower ignition power and ignition energy, and higher energy output compared to the initiator in Ref.…”

“…The fundamental principle of the diagnosis model has been described in detail in another article published in Journal of Applied Physics. 15,16 The explosion temperature versus its duration as a function of time for one typical igniter discharged in 40 V is shown in 8. After the electrical breakdown is realized, the temperature increases initially with the time and keeps an approximately constant value of 3500 C for 1.4 ms, then decreased.…”

Electro-explosion performance of KNO3-filled carbon nanotubes initiator

“…[6][7][8][9] Recent interest in electropyrotechnic initiator focuses on reactive nano-multilayer energetic films, such as Al/Ni, Al/Ti, B/Ti, Al/CuO, and Ti/CuO. 1, [8][9][10][11][12][13][14][15] The reaction heat of this MIC (metastable intermolecular composite) is very high, but the easy oxidation of the reactants and spontaneous reaction of these nano-multilayer films can impact the stability of the initiator. Many researchers reported the influence of carbon materials (carbon black, graphite, fullerene soot, C 60 , carbon fiber, CNTs) in the reaction of various propellants or explosives.…”
