“…[1] Nitrocellulose (NC), a typical EMs that has been widely used as a main energy ingredient and an essential role of skeleton support in single-base propellants, double-base propellants, or tri-base propellants, because of its unique features, such as excellent mechanical strength, flammability, rapid drying rate, and compatibility with several stabilizers and plasticizer. [2][3][4] In addition, the application fields of NC with different nitrogen content are also variant, for example, NC with nitrogen content of 10.7-12.3% is widely used in printing ink, varnishes, enamels, dyes, and adhesives; [5,6] while the nitrogen content larger than 12.3% is always used as the energetic materials. [7,8] On the other hand, RDX (cyclotrimethylenetrinitramine), HMX (cyclotetramethylenetetranitramine), and CL-20 (Hexanitrohexaazaisowurtzitan), as the three typical reported nitramine explosives, have exhibited promising and extensive applications in the field of propellants, explosives, and pyrotechnics because of its outstanding energy characters.…”

In order to investigate the thermal decomposition kinetics and mechanism of nitrocellulose (NC) based nitramine explosives nanocomposite energetic materials, this work prepares NC/RDX (cyclotrimethylenetrinitramine), NC/HMX (cyclotetramethylenetetranitramine), and NC/CL-20 (hexanitrohexaazaisowurtzitane) composites by a combined sol-gel and the freeze-drying technology. The structure is systematically investigated and the results reveal that the explosive particles are dispersed, filled, or embedded homogenously in the gel matrix of NC, thereby restricting the crystal growth of RDX, HMX, CL-20 particles to coarse and achieving submicron/nanometer. The thermal analysis of composites exhibits much lower peak temperature compared with raw explosive crystal, furthermore, the activation energy (E a ) of composites is also lower than that of both NC and explosives. Hence, the unique structure of NC gel matrix embedded explosives inside demonstrated different mechanism of decomposition. Concretely, the rupture of the H-NCO = O bond in the cross-linked structure is detected firstly, subsequently, the macromolecular chains' scission site of gel firstly occurs at -C-O-C-in the ring, and then the scission of -NO 2 (from NC or explosive crystals) bonds happened. Hence, this study may provide promising fabrication strategy and basic theory for the application of NC-based nanocomposite energetics in high-energy propellants and explosives.

“…Thermal analysis gives fast results and requires lower amounts of sample, although may not be representative of the whole propellant grain. Nevertheless, DSC and TG provide good hints about the compatibility when new molecules are being tested to be used as stabilizers, and it was already reported in the literature (Chelouche et al, 2020;Krabbendam-La Haye et al, 2003;Li et al, 2020;.…”

In this work we investigated the possibility of substituting diphenylamine (DPA) by the natural product guaiacol, as a stabilizer for nitrocellulose (NC)-based propellants. Stability evaluation, using heat-ux calorimetry (HFC), revealed lower heat ows associated with our guaiacol-stabilized propellant samples when compared to those of propellants stabilized with the traditional stabilizers. Also, pressure-vacuum stability tests (PVST) showed that our propellant exhibited lower evolved gas volumes. Traditional tests, such as the German Test, and the Bergmann-Junk Test, scored a NO volume, after titration, of 0.87 ml (below the limit-value for acceptance, which is 2.0 ml), and the Storage Test, showed that our samples are stable and do not degrade for more than 3 days when submitted to a constant temperature of 100°C. The homogeneity, stability and compatibility of our samples were evaluated through scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and isothermal thermogravimetry (TG).Ballistic parameters were estimated using a closed vessel along with ad hoc codes, for comparison purposes. Finally, a high-performance liquid chromatography (HPLC) method developed before allowed inferring the stabilizer consumption after arti cial ageing of samples. Such method also showed that the material met the correspondent stability criteria (AOP-48). In short, our results clearly indicate that guaiacol is an effective and e cient substitute for DPA as a propellant stabilizer for single base nitrocellulose-based propellants, making them more environmentally friendly.
