Elucidating the effect of nitrocellulose-encapsulated MgAl–CuO on the thermal behavior of double base propellant based on nitrocellulose and diethylene glycol dinitrate

Click Chemistry for Linker-Free BAMO-Based Energetic Sequence-Controlled Copolymers

“…Furthermore, P(BAMO-alt-EG) showed better energetic performance and reactivity than P(BAMO-alt-THF). This behavior was highlighted by the increase in the heat release accompanied by the drop in the activation energy after the addition of the EG unit . It can also be deduced that the evolution trends of log (A) and Ea versus conversion for the two binders are analogous, which can be related to the compensation effect phenomenon. , …”

“…Table presents the average values of Ea and log­(A) with their respective confidence intervals . The method described in this study allows for the preparation of ESCPs free from chain extenders, and the resulting polymers exhibit proper thermal stability compared to traditional energetic copolymers …”

“…Table 4 presents the average values of Ea and log(A) with their respective confidence intervals. 46 The method described in this study allows for the preparation of ESCPs free from chain extenders, and the resulting polymers exhibit proper thermal stability compared to traditional energetic copolymers. 47 By using the nonisothermal FWO method, we can obtain the value of apparent activation energy of the pyrolysis for P(BAMO-alt-EG)-2 and P(BAMO-alt-THF)-1 at different values of extent.…”

Electrochemical Synthesis of the Energetic Combustion Catalyst Co(BODN)·9H2O and Its Catalytic Effect on Ammonium Perchlorate Thermal Decomposition

“…These catalysts can effectively reduce the high-temperature decomposition (HTD) temperature of AP. However, these catalysts are inert and may decrease the integrated energy density of composite solid propellants with the increase in their addition amount. − The use of energetic combustion catalysts, such as (M­[BTE]­[H 2 O] 5 ) n (M = Sr, Ba, H 2 BTE = 1,2-bis­[tetrazol-5-yl]­ethane) and M­(5-ATZ) 4 Cl 2 (M = Cu, Co, 5-ATZ = 5-aminotetrazole), NC@MgAl-CuO (NC = nitrocellulose) and Ni­(MTZ) 4 (CBH) 2 (MTZ = 1-methyl-1,2,4-triazole, CBH = cyanoborohydride), to solve the above problem has attracted increasing attention. These energetic catalysts can not only reduce the decomposition peak temperature of AP but also increase the heat released by AP.…”
