“…As observed from the plotted DSC thermograms plotted, NC and NMCC polymers display only one exothermic process that occurred at maximum peak temperatures of 204.5 °C and 199.1 °C, respectively, which is assigned to the well-known thermolysis pathway of nitrated cellulosic chains [ 9 , 26 ]. Pure HNTO, however, undergoes two consecutive exothermic events within the range of 205–220 °C and 220–235 °C, similar to what is commonly reported in previous works [ 25 , 27 ]. For the physical mixtures, there were still three independent exothermic peaks, corresponding to the thermal decomposition of single nitrated cellulosic binders and HNTO, suggesting that there is no chemical reaction between components of the mixture.…”

This research aims to develop new high-energy dense ordinary- and nano-energetic composites based on hydrazine 3-nitro-1,2,4-triazol-5-one (HNTO) and nitrated cellulose and nanostructured nitrocellulose (NC and NMCC). The elaborated energetic formulations (HNTO/NC and HNTO/NMCC) were fully characterized in terms of their chemical compatibility, morphology, thermal stability, and energetic performance. The experimental findings implied that the designed HNTO/NC and HNTO/NMCC formulations have good compatibilities with attractive characteristics such as density greater than 1.780 g/cm3 and impact sensitivity around 6 J. Furthermore, theoretical performance calculations (EXPLO5 V6.04) displayed that the optimal composition of the as-prepared energetic composites yielded excellent specific impulses and detonation velocities, which increased from 205.7 s and 7908 m/s for HNTO/NC to 209.6 s and 8064 m/s for HNTO/NMCC. Moreover, deep insight on the multi-step kinetic behaviors of the as-prepared formulations was provided based on the measured DSC data combined with isoconversional kinetic methods. It is revealed that both energetic composites undergo three consecutive exothermic events with satisfactory activation energies in the range of 139–166 kJ/mol for HNTO/NC and 119–134 kJ/mol for HNTO/NMCC. Overall, this research displayed that the new developed nanoenergetic composite based on nitrated cellulose nanostructure could serve as a promising candidate for practical applications in solid rocket propellants and composite explosives.

“…An important aspect in studying energetic binders includes the measurement of the kinetics and the associated Arrhenius parameters of their decomposition [12][13][14][15]. Because such information is valuable for specifying the reaction pathways, and the kinetic constants are required to define the burning or explosion process.…”

“…Thermal analysis techniques, especially differential scanning calorimetry (DSC) technique, are powerful systems for acquiring thermal decomposition and kinetic parameters on energetic materials [18]. The main purposes are to determine the thermal stability [19,20] and mechanism of thermolysis reaction [21] and to provide valuable information about lifetime and conditions of storage, transportation [22]. Several studies on thermal decomposition kinetics of energetic binders have been reported [1,2,10,20,23]; however, kinetic studies on thermal decomposition of PDNPA and DNPA/DNBA are scarce, nor have any thermal stability studies of two binders been reported.…”

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.
