“…This latter is another important parameter to consider when characterizing EMs, since it dictates its performance. 35,36 As expected, the co-crystal (1 : 1) is presented with a considerably high heat release value (1481 J g À1 ), which is clearly shown in Fig. 1B, whereas (1 : 6) co-crystal exhibited the lowest value among all the samples (600 J g À1 ).…”

“…The main goal of thermal decomposition experiments is to acquire accurate information on the reaction mechanism and the Arrhenius parameters of the degradation of EMs. 36 It is well known that the apparent energy of activation calculated by isoconversional method displays more detailed information about the process of thermal decomposition. 48,56 The thermal decomposition kinetics of the pure co-crystal HNTO/AN and its composites with T-Co and GO-T-Co-T are studied by using kinetic isoconversional approaches, namely, it-FWO, it-KAS, VYA and TAS.…”

“…Recently, our research group designed GO-doped transition metal (Co) complexes of T and assessed their catalytic effect toward ammonium perchlorate, RDX, and NTO. 35,36 However, to the best knowledge of the authors, such type of catalysts has never been applied as additive of energetic co-crystals. Besides that, the use of GO as catalytic support may play a synergistic effect with the other ingredients, which will enhance the stability as well the decomposition efficient of the developed energetic co-crystals.…”

“…In 2011, the International Federation Dynamics Committee recommended the use of equal conversion rate kinetics method to calculate the relevant kinetic parameters in the thermal decomposition process, because they are more accurate than the single heating rate process 31 . However, the method of equal conversion rate needs to consider relevant reaction model, and the calculation is more complicated.…”

The existing stabilizers for nitrocellulose (NC) have various disadvantages of harming human health and polluting the environment, which does not meet the requirements of “green” propellants. This research work investigates the self‐polymerization of dopamine to prepare polydopamine (PDA) coated NC composites, and explores the effects of PDA on the thermal stability of NC. SEM, FT‐IR, and RAMAN were applied to investigate the changes of NC surface morphology and chemical structure. The results show that PDA is effectively coated on the NC surface and form a dense PDA film. The thermal decomposition behavior of NC was studied by TG and DSC, and the thermal decomposition activation energy was calculated. The results showed that the thermal stability of the physical mixture did not improve. The thermal stability of the complex increases first and then decreases with increasing of the concentration of dopamine hydrochloride. The optimal reaction conditions are that the concentration of dopamine hydrochloride is 3 g/L and the reaction time is 24 h. The thermal decomposition activation energy of the sample under the optimal conditions is 190.00 kJ/mol, 8.91% higher than that of NC (174.45 kJ/mol), which proves that PDA has the ability to improve the thermal stability of NC.

“…The information about the decomposition kinetics of materials can be obtained with the help of these experimental methods. The kinetics can not only judge the thermal stability of materials or the changes in decomposition mechanism [2][3][4] but also predict the runaway behavior of energetic materials under different environments. Hexahydro-1,3,5-trinitro-s-triazine (RDX) is an extremely important explosive component with its high energy density, high detonation velocity, and pressure.…”

RDX is an important and commonly used energetic material. The understanding thermal decomposition process of RDX is of great significance for the safety of its production, storage, and use. However, due to the coupling of phase transition and thermal decomposition process, a multi-step kinetic model including melting and decomposition process has not been established so far, which is not helpful to the prediction of its thermal behavior in different conditions. In this paper, Differential Scanning Calorimetry was used to measure the decomposition characteristics of RDX at different heating rates. A four-step consecutive reaction model A!A liq !B!C!D was established to depict the melting and decomposition process. Then quench and reheat experiments were performed to determine the types of each step, where the reaction types are autocatalytic except that the step of B!C is an N-order reaction. The model was used to predict the result of slow cook-off test. It was found that the predicted time of thermal explosion is 0.2 h earlier than the experiment and the onset temperature is 0.6°C smaller than experiment, which verifies the rationality of the kinetic model.
