ABSTRACT In this study, an ethylene vinyl acetate (EVA)/wax‐based thermoplastic propellant was prepared using a planetary mixer. High‐viscosity EVA used as the elastomer, and either solid wax based on oligomers or alternative liquid tributyl 2‐acetylcitrate (TBAC) were plasticizers to adjust its viscosity. This enhances flow characteristics reduces torque during mixing process. Results: The addition of 30 wt.% significantly reduced viscosity from 218.8 12.67 Pa s, whereas TBAC did not lead significant reduction in EVA. Designed with different ratios EVA/wax binder superior stress–strain relationship over polyurethane (PU). EVA/wax‐based has stable combustion at chamber pressures. St. Robert's Law provides equation for rate combustion, performance parameters derived internal ballistics simulation analysis are very valuable.

Abstract Catalytic stability is the prerequisite for catalyst to achieve high catalytic efficiency. This study finds a new path that Prussian Blue (PB) ultrathin nanosheet assembly material (PB‐NSa) designed and used reach efficient catalysis through continuous interaction with ammonium perchlorate (AP, component be catalyzed). Based on strong oxidation environment provided by AP, decomposition of PB occurs in advance, product Fe 2 O 3 accelerates AP can release large amount gas, then reacts disperses it near undecomposed finally realizing catalysis. The results show under PB‐N, “deactivation” stage thermal disappears, showing two consecutive exothermic stages, temperature peak reduced 341.1 °C, reduction range 73.1 °C. Combining kinetic calculation TG‐IR test, found PB‐NSa keep excellent stability, which depends its special structure AP. research provides design idea will greatly promote rapid industrialization.
