Assessment of electrostatic discharge sensitivity of nitrogen-rich heterocyclic energetic compounds and their salts as high energy-density dangerous compounds: A study of structural variables

Nitrogen-rich heterocyclic energetic compounds (NRHECs) and their salts have witnessed widespread synthesis in recent years. The substantial energy-density content within these compounds can lead to potentially dangerous explosive reactions when subjected to external stimuli such as electrical discharge. Therefore, developing a reliable model for predicting their electrostatic discharge sensitivity (ESD) becomes imperative. This study proposes a novel and straightforward model based on the presence of specific groups (–NH2 or -NH-, −N=N+−O− and –NNO2, -ONO2 or -NO2) under certain conditions to assess the ESD of NRHECs and their salts, employing interpretable structural parameters. Utilizing a comprehensive dataset comprising 54 ESD measurements of NRHECs and their salts, divided into 49/5 training/test sets, the model achieves promising results. The Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Maximum Error for the training set are reported as 0.16 J, 0.12 J, and 0.5 J, respectively. Notably, the ratios RMSE(training)/RMSE(test), MAE(training)/MAE(test), and Max Error(training)/Max Error(test) are all greater than 1.0, indicating the robust predictive capabilities of the model. The presented model demonstrates its efficacy in providing a reliable assessment of ESD for the targeted NRHECs and their salts, without the need for intricate computer codes or expert involvement.

Energetic characteristics of highly reactive Si nanoparticles prepared by magnesiothermic reduction of mesoporous SiO2

In this study, highly reactive silicon nanoparticles (h-Si) were successfully prepared by an improved magnesiothermic reduction process with ∼ 100 nm mesoporous silica nanoparticles as templates. The prepared h-Si have an average particle size of 18 nm, an active content of 85 %, and a specific surface area of 69.2 m2/g. Meanwhile, the preparation process is simple, green (avoiding the use of HF), and shows a great improvement in the inhibition of side reactions. The energetic characteristics of h-Si were compared with those of commercially available silicon nanoparticles (c-Si) by using ultrasonically mixed KClO4 as the oxidizer. Thermal analysis indicates that h-Si/KClO4 has an advanced reaction onset temperature, increased heat release, and lower reaction activation energy. In constant-volume combustion tests, h-Si/KClO4 shows excellent ignition and combustion characteristics in the fuel-rich state. In addition, electrostatic discharge sensitivity tests indicate that the minimum ignition energy of stoichiometric h-Si/KClO4 exceeds 100 mJ, which is much more insensitive than that of n-Al/KClO4 (∼2 mJ). Overall, h-Si show enhanced reactivity and have attractive advantages in applications where suitable combustion properties and low electrostatic sensitivity are required.

Coupling ultrasound and coaxial flow: Regulation of surface microstructure of zirconium powder assisted by microfluidics

The regulation of energy release characteristics and safety of highly active metal fuels has attracted significant attention. In response to the limitations of using hydrofluoric acid (HF) to modify zirconium (Zr) powder in batch reactors, a microfluidic method coupling ultrasound and coaxial flow microreactors was proposed to achieve the control of the microstructure on the surface of Zr powder. The fluid flow and mixing characteristics in the microreactor were analyzed using on-line detection devices, leading to the determination of suitable fluid parameters. Through analysis of the reaction process between Zr and HF, a reaction model based on the HF concentration was established and subsequently verified through a microreaction system. The results indicate that the HF concentration greatly influences the morphology and composition of Zr powder, thereby determining the material and structural transformation of the Zr powder surface. The excellent thermal oxidation performance and electrostatic safety of HF-modified Zr powder were confirmed through thermal analysis and electrostatic discharge sensitivity tests. This study provides valuable insights for controlling the microstructure and properties of ultrafine Zr powder.

Preparation, Characterization and Properties of NC-coated Zirconium Composite Particles

Zirconium has certain application advantages compared with other metals due to its high density, high volume calorific value and combustion performance. Unfortunately, the applications of current Zirconium powders are limited due to its high electrostatic discharge sensitivity, making Zirconium powders more pyrophoric and less amenable to functionalization. To improve the security, Zr/NC composite particles with reduced electrostatic discharge sensitivity are prepared by solvent-antisolvent method and characterized by FT-IR, XRD, TG, SEM and ESD test. The measurement confirmed that the 50% firing energy (E50) of Zr/NC is increased from 5.13 mJ to 25.2 mJ, which is 5 times higher than that of raw Zr powder. The results show that surface coating modification is a feasible method for decreasing the ESD of Zr powder. This study provides technology support for its application in high density propellant.

An effective catalyst carrier SiO2: Enhancing catalytic and combustion properties of CuFe2O4 on energetic components

To enhance the catalytic activity of copper ferrite (CuFe2O4) nanoparticle and promote its application as combustion catalyst, a low-cost silicon dioxide (SiO2) carrier was employed to construct a novel CuFe2O4/SiO2 binary composites via solvothermal method. The phase structure, morphology and catalytic activity of CuFe2O4/SiO2 composites were studied firstly, and thermal decomposition, combustion and safety performance of ammonium perchlorate (AP) and 1,3,5-trinitroperhydro-1,3,5-triazine (RDX) with it affecting were then systematically analyzed. The results show that CuFe2O4/SiO2 composite can remarkably either advance the decomposition peak temperature of AP and RDX, or reduce the apparent activation energy at their main decomposition zone. Moreover, the flame propagation rate of RDX was promoted by about 2.73 times with SiO2 content of 3 wt%, and safety property of energetic component was also improved greatly, in which depressing the electrostatic discharge sensitivity of pure RDX by about 1.89 times. In addition, the effective range of SiO2 carrier content in the binary catalyst is found to be 3 to 5 wt%. Therefore, SiO2 opens a new insight on the design of combustion catalyst carrier and will promote the application of CuFe2O4 catalyst in solid propellant.

High dispersity and ultralight PVP-mediated Al/MFe2O4/g-C3N4 (M = Cu, Mg, Ni) nanothermites synthesized by a novel sol-freeze-drying technology

Nanothermite is a reactive system of nanoscale metal-based energetic materials, which is also known as metastable intermolecular composites (MICs). In this study, graphitic carbon nitride (g-C3N4) as a new typical polymer semiconductor was firstly employed to replace GO as an additive in nanothermite. For solving the dispersity of g-C3N4 in nanothermite, a simple and novel sol-freeze-drying technology was firstly proposed to prepare Al/MFe2O4/g-C3N4 (M = Cu, Mg, Ni). The as-prepared Al/MFe2O4/g-C3N4 (M = Cu, Mg, Ni) nanothermites present a similar shape to the host container and have high dispersity, ultralight weight (0.035 g·cm−3) and large specific volume (28.19 cm3·g−1). The optimal PVP and g-C3N4 content were determined. Al/MFe2O4/g-C3N4 (M = Cu, Mg, Ni) all have superior combustion performance, lower electrostatic discharge sensitivity (EDS) and better catalytic performance on ammonium perchlorate (AP) and dihydroxy-lammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50). g-C3N4 plays an important role in suppressing unstable combustion and is beneficial to reduce the electrostatic discharge sensitivity of MICs. This work demonstrates that PVP-mediated sol-freeze-drying technology is an effective approach for obtaining g-C3N4-based nanothermite with high dispersity and ultralight characteristic.

Al/SnO2 Nanothermite ESD Desensitization by Means of the Elaboration of Tailored SnO2-Polypyrrole Composites.

Incidents can occur when handling energetic materials (EMs) due to their sensitivity to external stimuli. Mechanical (friction, impact) and electrical (electrostatic discharge (ESD)) stimuli can trigger involuntary ignition of EMs. Nanothermites, defined as highly reactive mixtures of a metal and a metal oxide, show interesting reactive properties (high temperature/amount of heat). However, their extreme sensitivity to ESD is a significant drawback in their development. With a sensitivity threshold of lower than a millijoule and considering the human body capacity discharge is a few tens of millijoules, the handling of such energetic mixtures is extremely hazardous. ESD desensitization is therefore of crucial importance for the use of these materials. To achieve this goal, polypyrrole (PPy) conductive polymer was used as an additive within an Al/SnO2 energetic formulation. This polymer is able to easily conduct the electrostatic charges, which is useful to avoid an ignition after a spark stimulus. PPy was added to the nanothermite through the elaboration of SnO2-PPy composites. Delaying the SnO2 introduction time during pyrrole's polymerization (t = 0, 1, 24 h) changed the microstructures of the composites. The various SnO2-PPy composites highlighted that the additive's distribution within the composite is a key component for the modulation of ESD sensitivity. For example, this threshold is higher for a nanothermite formulated with the composite elaborated at t = 0 h (96.5 mJ with 7.5 vol % of polymer) than a composition based on the composite at t = 24 h (16.9 mJ with 8.2 vol % of polymer). Meanwhile, the reactive properties are decreased. The loss of reactivity (e.g. combustion speed) was explained by the thermal insulating property of the additive. Overall, the aim of this study is to help in the understanding of ESD desensitization of nanothermites in order to make them safer for operators and adapted to the required applications.

Modulation of Crystal Growth of an Energetic Metal–Organic Framework on the Surfaces of Graphene Derivatives for Improved Detonation Performance

Energetic materials are a special class of energy materials composed of C, H, O, and N. Their safety always deteriorates with increasing energy. Regulating the properties of energetic materials to meet application requirements is one of the focuses of research in this field. Energetic metal-organic frameworks (EMOFs) are good candidates as primary explosives to replace lead azide (LA) and other explosives containing toxic metal elements. However, safety remains the biggest concern in applications. In this paper, crystal morphology modulation of EMOF was carried out by stepwise coordination of metal ions and energetic ligands on surfaces of graphene oxide (GO) and amino-functionalized graphene oxide (AGO). Two energetic composite materials, Cu-AFTO@GO and Cu-AFTO@AGO, were successfully synthesized and also the EMOF (Cu-AFTO). The structures and morphologies of these materials were fully characterized. The thermal decomposition behaviors, mechanical sensitivity, and electrostatic discharge sensitivity were investigated in detail. The electric ignition ability of EMOF and two composite materials was tested. This study shows that it is possible to reduce the diameter of EMOF crystals from hundreds of microns to tens of nanometers by a stepwise coordination method. The high electrical conductivity and sensitivity-reducing effect of GO and/or AGO allow the nanosized EMOF crystals to have a lower ignition threshold and lower sensitivity.

Investigation of electrical resistivity and electrostatic discharge sensitivity of Mg/ Ba(NO3)2/novolac resin composite

Each composite energetic material (CEM) has specific electrical resistivity (ER) and electrostatic discharge (ESD) sensitivity. These parameters depend on the concentration of composite ingredients. The effect of different mole ratios of ingredients on the ER and ESD sensitivity of Mg/Ba(NO3)2/novolac resin composite was modeled by response surface methodology (RSM) and central composite design (CCD). Nonlinear regression analysis and analysis of variance (ANOVA) indicated that the predicted responses were in good agreement with the experimental results. The results showed an inversely proportional correlation between increasing the mole ratio of Mg with ER and the minimum ignition energy (MIE) of ESD ignition. Similarly, there is a directly proportional correlation between increasing the mole ratio of Ba(NO3)2 and the novolac resin with increasing ER and MIE. A composite with low ER will conduct electrical energy and accumulate joule heating to begin ESD ignition. Therefore, increasing the conductive Mg ratio in the composite decreases joule heating. Thus, the MIE decreases with an increase in the Mg concentration. Similarly, increasing the concentration of electrical insulated novolac resin or Ba(NO3)2 in the composite increases the joule heating and the MIE. Therefore, a correlation was made to predict the ESD sensitivity of composites with different mole ratios of ingredients according to the values obtained from their ER measurements.

Effect of Ingredients Ratio on the Friction Sensitivity and Burning Performances of Mg/Ba(NO3)2/Novolac Resin Pyrotechnic Compositions

AbstractEach pyrotechnic composition has specific sensitivity such as electrostatic discharge (ESD) sensitivity and friction sensitivity (FS), and it also has specific ignition performance, including luminous intensity (LI) and burning rate (BR). These parameters depend on the concentration of pyrotechnic composition ingredients. In this study, Mg/Ba(NO3)2/novolac resin compositions were prepared using different weight ratios (wt.%) of Mg, Ba(NO3)2, and novolac resin. Then, they were investigated by their FS, LI, and BR. The results showed that by increasing Ba(NO3)2 concentration from 33.76 to 84.54 wt.% Ba(NO3)2, the FS increases from 343 N to 65.5 N. However, the LI and BR of this composition increased by increasing Ba(NO3)2 concentration until a 3/1 stoichiometric ratio of Mg/Ba(NO3)2 (from 13086 to 20588 cd (candela) and 11.25 to 13.71 cm/s, respectively for 33.76 to 64.92 wt.% Ba(NO3)2) and decreased afterward (from 20488 to 53.24 cd and 13.71 to 6.45 cm/s, respectively). For Mg/Ba(NO3)2/novolac resin containing 3 to 12 wt.% novolac resin FS increased from 56 to above 360 N. LI and BR decreased from 20057 to 1203 cd and 17.3 to 1.2 cm/s, respectively. The stoichiometric ratio of Mg/Ba(NO3)2 has the highest enthalpy of reaction. Therefore, it can be concluded that it has the highest LI and BR.

Spark Desensitization of Nanothermites via the Addition of Highly Electro-Conductive Carbon Particles

In the past decade, the formulation of spark-desensitized nanothermites has considerably advanced, making them safe to handle. When ignited, these materials reveal impressive properties such as high temperatures (>1000 °C), intense heat releases (>kJ/cm3), and sometimes gas generation. Unfortunately, these energetic systems are systematically characterized by an extreme sensitivity to electrostatic discharges, which can cause accidental ignitions during preparation, handling, and transport. The present study examines the electrostatic discharge sensitivity response of an Al/WO3 energetic formulation doped with highly conductive carbon nanoparticles (Ketjenblack EC600JD). The results showed an increased threshold from <0.14 mJ to almost 40 mJ with 18.80 vol. % of KB EC600JD in the energetic mixture. The energetic material was also desensitized to friction stress with a threshold greater than 360 N, in contrast to a value of <4.9 N for an un-doped Al/WO3 energetic composite material. The reactive performance of the system (w/o Ketjenblack additive) was verified in open medium by means of an optical igniter. The heat release was determined by a calorimetric bomb and a decrease of 50% was recorded for the carbon-doped energetic system compared to the pristine Al/WO3 composition.

Self-assembly preparation of advanced metastable MCo2O4/GO/Al (M=Cu, Mg, Zn, Ni) nanothermites to realize large heat release, stable combustion and high safety

Metal/oxide-based nanothermite is a kind of metastable intermolecular composites (MICs) whose application performance can be adjusted purposefully by varying properties of oxidizers. Herein, four new MCo2O4/GO/Al (M = Cu, Mg, Zn, Ni) nanothermites were prepared in this work, in which the bimetallic composite oxides of spinel MCo2O4 were employed to replace single metal oxides as oxidizer. The positively charged MCo2O4 and Al nanoparticles were successfully self-assembled by the encapsulation of negatively charged GO. MCo2O4/GO/Al nanothermites present a dense layer stacked structure and uniform distribution, with a favorable interfacial contact between the bimetallic oxide and fuel at the nanoscale. MCo2O4/GO/Al nanothermites release higher energy of about 2500–3400 J g−1, much higher than that of corresponding thermite with single metal oxide. CuCo2O4/GO(2.5 wt%)/Al has the shortest pressure rise time (27.18 ms), largest energy output (3422 J g−1) and peak pressure (6.03 MPa), exhibiting a more violent combustion reaction and higher reactivity. The introduction of GO significantly improves the safety, and the electrostatic discharge sensitivity (EDS) of CuCo2O4/GO(5 wt%)/Al can reach 0.56 mJ, largely higher than that of CuCo2O4/Al without GO (0.04 mJ). MCo2O4/GO/Al nanothermites also have different catalytic performances on energetic components of cyclotrimethylenetrinitramine (RDX), ammonium perchlorate (AP) and dihydroxy-lammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50), indicating the selectivity of catalyst. This study proves that spinel MCo2O4 is a superior oxidizer for Al-based nanothermite system.

An excellent synergy between CL-20 and nanothermites in flaming and propelling with high specific impulse and superior safety to electrostatic discharge

Nanothermites possess much attentions relying on potential probability to the fields of the military and civilian. Whereas, the practical applications for nanothermites have been limited by the high electrostatic discharge (ESD) sensitivity and little gas generation, which is a pronounced problem in the microthruster particularly. In this work, the two typical nanothermites (Al/CuO and Al/MoO3, as Al/MXOY) were assembled with various contents of CL-20 to be defined Al/MXOY@CL-20. The characteristics of Al/MXOY@CL-20 were examined by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), powder X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The ignition properties of Al/MXOY@CL-20, such as burning rate, the unrestrained combustion, ignition temperature, delay time, pressurization and propulsion properties, were studied. In addition, the energy required for 50% ignition probability (E50) was applied to evaluating the sensitivity of Al/MXOY@CL-20 to ESD. Results revealed that the total heat release for Al/MXOY@CL-20 was increased on account of CL-20, and CL-20 facilitated the transformation of CuO to Cu2O. The burning rates decreased with the increase of CL-20, whereas the burning rate of Al/MoO3@10%CL-20 was little higher than that of Al/MoO3. Al/CuO@10%CL-20 and Al/MoO3@30%CL-20 exhibited superior performances respectively for the maximum flame area, the lowest ignition temperature, the highest pressurization rate and specific impulse. The particular significance was that CL-20 played a positive role for Al/MXOY@CL-20 on the safety to ESD. For instance, the E50 of Al/CuO@50%CL-20 was 163.84 mJ meanwhile Al/CuO of that was 0.24 mJ. In conclusion, in the light of the superior specific impulse and the excellent safety to ESD, Al/MXOY@CL-20 (especially Al/CuO@10%CL-20 and Al/MoO3@30%CL-20) would possess the remarkable application prospects for practice in the microthruster.

Effects of Low-Level Gamma Radiation on Common Nitroaromatic, Nitramine, and Nitrate Ester Explosives.

The aging of high explosives in an ionizing radiation field is not well understood, and little work has been done in the low dose and low dose rate regime. In this study, four explosives were exposed to low-level gamma irradiation from a 137Cs source: PETN, PATO, and PBX 9501 both with and without the Irganox 1010 stabilizer. Post-irradiation analysis included GC–MS of the headspace gas, SEM of the pellets and powder, NMR spectroscopy, DSC analysis, impact sensitivity tests, and ESD sensitivity tests. Overall, no significant change to the materials was seen for the dose and dose rate explored in this study. A small change in the 1H NMR spectrum of PETN was observed and SEM and ESD results suggest a surface energy change in PATO, but these differences are minor and do not appear to have a substantial impact on the handling safety.

Determination by standardized test methods of electrostatic discharge sensitivity of electric igniters in order to prevent their unexpected initiation

In the case of use of the electric igniters, in various applications, depending on their field of use, there may be a risk of unexpected initiation by means of electrostatic discharges from persons, their clothing and / or objects isolated from the ground. Electrification and consequently the accumulation of dangerous electrostatic potentials on people and on their outerwear, generally takes place during the performance of work tasks, a situation in which due to the movements performed by the persons involved, there is the phenomenon of friction between different parts of clothing or between clothing and the person wearing the clothing. The presence of the risk of unexpected initiation of electric igniters by electrostatic discharge requires the adoption and implementation of measures to minimize their effects on the safety and health of workers and others. In view of the above, determining the performance of sensitivity of electric igniters to unexpected initiation by electrostatic discharge is very important as this depends on the safety and security of workers / persons involved in activities that require the use of these elements / products.

Experiments and failure analysis of a charged board event on a hard disk drive printed circuit board assembly

A charged board event on a hard disk drive printed circuit board assembly was experimentally measured under the charged device model concept. Electrostatic discharge sensitivity was measured and used for establishing an electrostatic discharge control program for a hard disk drive assembly process. The results revealed that a sample printed circuit board was damaged when subjected to +2500 V. The tested hard disk drive could not initialize while some copper traces were melted and disconnected. This classification can be a guideline for managing manufacturing processes using essential insulators to mitigate field induced potentials in hard disk drive assembly.

Bio-inspired synthesis of RDX@polydopamine@TiO2 double layer core–shell energetic composites with reduced impact and electrostatic discharge sensitivities

To reduce the impact and electrostatic discharge sensitivities of RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), the polydopamine (PDA) and amorphous TiO2 were used as shell materials to construct a series of RDX@PDA@TiO2 double layer core–shell energetic composites with an RDX as the inner core and amorphous TiO2 as the exterior shell; and the PDA was employed as bio-adhesive agent coated on the surface of RDX to enhance the interfacial adhesion between RDX and amorphous TiO2. Then, by the characteristics of scanning electron microscopy (SEM), flourier-transform infrared (FT-IR) spectra, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), the double layer core–shell structure of RDX@PDA@TiO2 composites was indicated; and the reaction mechanism of the depositions of amorphous TiO2 shell was proposed. Furthermore, we explored the influence of different content, morphologies of amorphous TiO2 shell and thickness of PDA on the desensitization effect of RDX@PDA@TiO2 composites. Compared with pure RDX, the RDX@PDA@TiO2-1#, -2#, -3#, -4#, -5# samples exhibited significant enhancement of 4.0 J (26.7%), 15.3 J (102.0%), 28.2 J (188.0%), 30.0 J (200.0%), 21.8 J (145.3%) of impact energy, and 0.7 (50.0%), 1.0 J (71.4%), 2.2 J (157.1%), 7.2 J (514.3%), 5.9 J (421.4%) of electrostatic discharge energy, respectively. And the prepared RDX@PDA@TiO2 composites with thicker and lager particle size of amorphous TiO2 shell leaded to better desensitization effect. This work potentially provided an alternative method for improving vulnerability and transportation safety of RDX.

Improvement of electrostatic discharge sensitivity of lead styphnate particles using some polymer coating agents

ABSTRACT This work is devoted to reducing the electrostatic discharge sensitivity of lead styphnate (LS) particles by using the microencapsulation technique involving the solvent/non-solvent method in which viton A and nitrocellulose are used as coating agents. Improvement in quality and sensitivity of LS particles were studied by using friction, impact, electrostatic discharge and flash point tests. Electrostatic discharge sensitivity results confirmed the better performance of samples coated with viton A compared to nitrocellulose. Based on the experimental results, the most desensitized lead styphnate particles were obtained by using 5% (w/w) of viton A as the coating agent and electrostatic discharge sensitivity increasing from 0.4 to 1 mJ.

Cover Image, Volume 138, Issue 29

Nanothermites are energetic composite materials made of a reducing metal and a metal oxide at the nanometric scale. Their combustion reaction is characterized by a high combustion temperature (>2000 K) combined with an intense heat release (kJ/cm3). However, their extreme sensitivity to electrostatic discharges (< 0.14 mJ) can lead to an accidental ignition during their handling. This cover designed by Pierre Gibot and Virginie Goetz presents the combustion behavior of an aluminum/tin (IV) oxide energetic composite material (Al/SnO2) enriched with a low concentration of conducting polymer (polypyrrole, PPy - 12.2 wt.%) mitigating its electrostatic discharge sensitivity (56 mJ) while maintaining reactive properties. This study represents a promising solution for solving safety problems in pyrotechnics. DOI: 10.1002/app.50752

Polypyrrole material for the electrostatic discharge sensitivity mitigation of Al/SnO2 energetic composites

AbstractNanothermites are composite energetic materials made of fuel and oxidizer nanoparticles characterized by impressive exothermic reactions (highly flame temperatures and impressive heat combustion releases). However, nanothermites suffer from their high electrostatic discharge (ESD) sensitivity that may be at the origin of accidental ignitions during handling. The present study deals with the use of doped‐polypyrrole conducting polymer in aluminum/tin (IV) oxide energetic formulation (Al/SnO2). X‐ray diffraction, Fourier transforms infrared spectroscopy, scanning electron microscopy, conductivity measurements, sensitivities and combustion tests were implemented to characterize the polypyrrole‐doped Al/SnO2 energetic composite. The results revealed a significant gradual ESD desensitization of the nanothermite (&lt;0.14 mJ to 246.40 mJ) as a function of the doped‐polypyrrole amount (0 to 15 wt%). The reactive properties of the polypyrrole‐enriched Al/SnO2 nanothermite were verified and an acceptable reactive behavior was claimed. The successful adding of doped‐polypyrrole conducting polymer within energetic nanocomposites is reported for the first time.
