“…It has been reported that graphene and graphene oxide derivatives are capable of constructing a conductive network that facilitates the heat and electron transfers during fuel decompositions, producing an improved energy release and decomposition of AP. 54,55 Dey et al 56 evaluated graphene as a catalyst of the decomposition of AP with a 5% wt., registering a rst exothermic peak at 305 C and diminishing the HTD process of AP by 6 C. Zhao and coworkers tested GO at 2% wt., observing two peaks for the low-and high-temperature decomposition at 345 and 430 C respectively, 57 diminishing the HTD by 3 C. A study published by Memon and coworkers 54 reported that fast crash AP with hand-mixed GO decreased the second decomposition temperature of AP by 26 C, while fast crash AP and GO reduced the nal decomposition temperature to 32 C.…”

“…While the conducting properties of desensitizers are exploited when the energetic composite is submitted to the spark test, their lubricant properties are solicited during the friction phenomena. The different compounds were added either as “isolated/individual” nanoparticles within the fuel/oxidizer energetic composite or through the synthesis of a desensitizer/oxidizer or a desensitizer/fuel composite before it was mixed with the fuel or the metal oxide to form the final energetic mixture. The use of polyaniline conducting polymer (PAni) as an additive is particularly interesting and promising, as reported by Gibot et al .…”

Nanothermites consisting of a reducing metal and a metal oxide nanopowder represent a new generation of energetic materials in pyrotechnics due to their impressive reactive properties. However, their extreme sensitivity regarding electrostatic discharge appears to be detrimental to their future practical applications. Herein, the mitigation of the sensitivity thresholds of the aluminium/tin (IV) oxide energetic nanocomposite is successfully achieved by using a conducting polymer, polyaniline (PAni). PAni was introduced within the thermite by the chemical polymerization of an oxidizer/PAni hybrid matrix. The SnO 2 -PAni composites were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, electrical conductivity measurements, and transmission electron microscopy. The derived Al/SnO 2 -PAni thermites were investigated in terms of sensitivities and reactivity. Results revealed gradual desensitization of the Al/SnO 2 thermite as a function of the concentration of PAni for both the electrostatic discharge (0.14-1212 mJ) and friction (216-360 N) tests while maintaining reactive energetic composites. This work presents a way for the preparation of insensitive and reactive energetic formulations.

“…Extensive researches of graphene and graphene oxide (GO) in EM have been conducted, and their significant desensitization on energetic crystal have been verified. [3,19,30] Considering its similar structure with graphene, the soft hBNNS also can be applied as desensitization material and thermal stabilizer in the field EM, while there is few relevant reference so far. Unfortunately, the surfaces of inorganic hBNNS are hydrophilic while that of organic energetic crystal is hydrophobic.…”

tetraoxaisowurtzitane (TEX), [8] and so forth. However, long-terms of researches manifest that there exist two opposite aspects in most HEDMs since the inherent defects of their molecular structures, the contradiction between high energy and low sensitivity. [9,10] Most powerful energetic materials are susceptible to external stimulations, and the investigation and storage of them may bring momentous disaster. Several strategies have been used to address this problem so far, such as designing and synthesizing new energetic compounds, [11-13] morphology optimization of EM, [14] cocrystallization with low sensitivity energetic crystals, [15] and preparing polymer bonded explosive (PBX). [16-18] Among these approaches, PBXs consisting of 90-95 wt% of energetic crystals and 5-10 wt% of polymer binder or other components is facile and efficient, which can combine the merits of polymer materials without destroying the inherent structures of energetic crystals. [19] One of the key indicators evaluating the PBXs is the coverage degree of fillers on energetic crystals, while it is not ideal by the traditional method such as water suspension and kneading. [20] Up to now, it has been proved that in situ polymerization is an important and matured way to construct polymer coated core-shell structures, [21,22] and it is also applied to prepare the core-shell energetic materials. [10,16,20] 1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane (HMX) has been regarded as a kind of high-performance explosive with good thermal stability, high energy and density, and has extensive application in aerospace industry and military engineering. However, the high sensitivity remains the major constraint to its applications. In our previous works, we have prepared the HMX@urea-formaldehyde (UF) composites and HMX@polyaniline (PANI) composites with significant reduced sensitivity via in situ polymerization.
