“…For BMMT, the peaks at 1296 and 1198 cm −1 were due to the P═O bending vibration and C―O vibration of aromatic rings, respectively. The peak at 960 cm −1 could be assigned to the P―O―C stretching vibration, whereas those at 778 and 688 cm −1 are originated from mono‐substituted aromatic rings, which indicated the successful modification by BDP.…”

Summary Polystyrene‐b‐(ethylene‐co‐butylene)‐b‐styrene (SEBS) is a widely used thermoplastic elastomer. However, it suffers from poor flame retardancy. Proper combination of organic‐modified montmorillonite and intumescent flame retardant (IFR) works but is not stable due to easy absorption of moisture. In this study, a novel and stable halogen‐free flame‐retardant system is demonstrated by encapsulating a hydrophobic organophosphate, ie, bisphenol A bis (diphenyl phosphate) (BDP) into a stable micelle and then “attaching” the BDP micelles to the montmorillonite (called: side‐intercalation). The resulted BDP modified montmorillonite (BMMT) has a large inter‐platelet spacing and demonstrated synergistic effect with IFR on flame retardancy, tensile property, and water resistance for the composite with SEBS. In addition to more homogeneous dispersion of IFR and BMMT, a longer‐lasting interfacial interaction between IFR and SEBS matrix with addition of small amount of BMMT also plays the role. The results suggest that BMMT can serve as an effective additive for formulating novel halogen‐free flame retardants for the SEBS to meet increasingly stricter environmental requirements.

“…To further confirm the possible reaction mechanism functions, the differential master plot method, which is defined by Equation 5, can be applied [51]. Figure 5d shows the theoretical f(α)/f(0.5) curves for different models (lines), and four experimental f(α)/f(0.5) results (symbols) obtained by using Equation (5). It can be seen from Figure 5d that the experimental f(α)/f(0.5) results The corresponding non-isothermal conversion (α-T) curves for the thermal decomposition process of Ni(DMG) 2 complex at the different heating rates are shown in Figure 5b.…”

“…Combustion catalysts, as one of the main ingredients, play an essential role in the modification of the burning rate and combustion stability of solid propellants [1][2][3]. A variety of combustion catalysts, such as transition metal oxides (e.g., CuO, PbO, NiO) [4][5][6][7][8], compounds (e.g., lead salicylate, copper adipate, copper salicylate) [9][10][11], and nano-metal particles (e.g., Ni, Bi) [12][13][14], have been up to now studied extensively. In the combustion process of solid propellants, the combustion catalyst acts as a heterogeneous catalyst, and its catalytic activity primarily depends on its active sites.…”

The fiber-like bis-(dimethylglyoximato) nickel(II) complex, Ni(DMG)2 was successfully synthesized. The obtained samples were characterized by SEM-EDS, FT-IR, XRD, and XPS. The TG-DSC-FTIR-MS coupling technique was used to characterize the thermal decomposition behavior and evolved gas analysis of Ni(DMG)2. The non-isothermal decomposition reaction kinetic parameters were obtained by both combined kinetic analysis and isoconversional Vyazovkin methods. It was found that Ni(DMG)2 begins to decompose at around 280 °C, and a sharp exothermic peak is observed in the DSC curve at about 308.2 °C at a heating rate of 10 °C·min−1. The main gaseous products are H2O, NH3, N2O, CO, and HCN, and the content of H2O is significantly higher than that of the others. The activation energy obtained by the combined kinetic analysis method is 170.61 ± 0.65 kJ·mol−1. The decomposition process can be described by the random nucleation and growth of the nuclei model. However, it was challenging to attempt to evaluate the reaction mechanism precisely by one ideal kinetic model.
