Abstract The combustion efficiency and reactivity of aluminum (Al) particles, as a crucial component in solid propellants, are constrained by the inert oxide layer (Al 2 O 3 ). Polytetrafluoroethylene (PTFE) can remove layer, however, carbon deposition generated during reaction process still limits Al/PTFE fuel. Here, litchi‐like fuel with nano‐PTFE islands distributed on Al particles surface is successfully designed, based localized activation synergistic strategies, to solve deposition. This unique PTFE‐coated structure achieve etching, creating channels, exposing active Al. Such channel network promotes circulation fluorine oxygen, stimulating reactions Al‐F Al‐O energy output. Regulating PTFE content maximize elimination full Al/PTFE. maximum flame area pressure output increased 241.9%, 734.7%, 118.4%, 265.2%, respectively, compared traditional physical mixture core‐shell fuels. effects effectively transform waste into valuable resource, introducing novel approach for propellants.

Incomplete combustion of Al in solid propellants can be effectively resolved by coating an oxidizer at the microscale. In this paper, Al@CL-20 composites with polydopamine as interfacial layer were prepared using strategy. The structure, heat reaction, thermal decomposition properties, and performances these under effects graphene oxide (GO) graphene-based carbohydrazide complexes (GO–CHZ-M, M = Co2+, Ni2+) have been comprehensively investigated. experimental results show that reaction is 6482 J g–1, which 561 g–1 higher than corresponding mechanical mixture. presence GO–CHZ-Co further increase to 6729 a decreased activation energy about 54.8%. Under synergistic effect control GO–CHZ-M, ignition delay time Al@CL-20-Co decreases from 5.1 4.2 ms. Besides, D50 condensed products (CCPs) 5.62 4.33 μm, indicating efficiency greatly improved.
