“…Because such information is valuable for specifying the reaction pathways, and the kinetic constants are required to define the burning or explosion process. However, obtaining these data under such conditions is so difficult [16,17]. Thermal analysis techniques, especially differential scanning calorimetry (DSC) technique, are powerful systems for acquiring thermal decomposition and kinetic parameters on energetic materials [18].…”

Thermal stability and decomposition kinetics of two energetic binders: poly (2,2-dinitropropyl acrylate) (PDNPA) and 2,2-dinitropropyl acrylate-2,2-dinitrobutyl acrylate copolymer (DNPA/DNBA) were investigated by thermogravimetry (TG) and differential scanning calorimetry (DSC) techniques under nitrogen atmosphere. The results of TG analysis revealed that the mass loss about 60 % of two energetic binders occurs in the temperature ranges of 200-280°C. Meanwhile, the decomposition temperature of PDNPA and DNPA/DNBA started at 183 and 198°C, respectively. The decomposition kinetics of two energetic binders were studied by non-isothermal DSC under various heating rates (2.5, 5, 7.5, 10 and 12.5°C min -1 ). The kinetic parameters for thermal decomposition of the both binders, such as activation energy and frequency factor, were obtained by ASTM E698, Kissinger-Akahira-Sunose (KAS) and Starink methods. The activation energy values obtained by KAS and Starink methods increase with the degree of conversion (a). The activation energy of thermal decomposition at a = 0.1 obtained by Starink and KAS methods for the PDNPA and DNPA/DNBA are 123.23 ± 0.13 and 127.71 ± 0.12 kJ mol -1 , respectively. The rate constants for thermal decomposition calculated from the activation parameters showed the structural dependency. The relative thermal stability of two polymers under 50°C was in this order: DNPA/DNBA [ PDNPA.

“…Examples include suitable mechanisms, decomposition rates, and the values of kinetic and thermodynamic parameters [8,9]. Furthermore, thermal analysis data permit the prediction of the critical ignition temperature and the shelf-life or half-life for an energetic compound at any given temperature [10][11][12]. These capabilities make thermal analysis techniques valuable tools in energetic materials characterization.…”

1,3,6,8-tetranitro carbazole (TNC) as a secondary explosive is used in composite explosive formulations in order to reduce the sensitivity and increase the stability of the explosive composites. In this work, the thermal stabilities of pure TNC and its nanocomposites prepared via three different nanoparticles were studied by thermal analysis, i.e. differential scanning calorimetery (DSC) and thermogravimetry (TG) techniques. Thermal analysis data revealed that the thermal behavior of pure TNC is significantly different from the nanocomposites studied. Pure TNC decomposed completely during a single step in the temperature range 385-425 °C. However, the addition of nanoparticles to the TNC powder leads to higher thermal stability in comparison with the pure TNC. The decomposition kinetics of TNC and its nanocomposites were studied by non-isothermal DSC at several heating rates. Thermokinetic and thermodynamic parameters corresponding to the thermal decomposition of pure TNC and nanocomposites were computed and compared. The results showed that the addition of nanoparticles to the TNC powder has a considerable effect on the thermal stability of the explosive.

The thermal behaviour of 1,3,6‐trinitrocarbazole (TENT) in the form of pure and nanocomposite explosives was examined by differential scanning calorimetry (DSC) and thermogravimetry (TG). Thermoanalytical data revealed that thermal decomposition of pure TENT is significantly different from the investigated nanocomposites. The results confirmed that pure TENT decomposed completely in a single stage in the temperature range 400–450 °C. Though, addition of the nanoparticles to the TENT powder leads to higher thermal stability in comparison with the pure TENT. Decomposition kinetics of the pure TENT and the nanocomposites were studied by non‐isothermal DSC at diverse heating rates. The resulted thermokinetic and thermodynamic parameters for the thermal decomposition of pure TENT were compared with the nanocomposites.
