Enhancing the thermal conductivity of polymer-bonded explosives via constructing a three-dimensional graphene network
The thermal conductivity of energetic materials significantly affects their safety and environmental adaptability. To enhance the thermal conductivity of polymer-bonded explosives (PBXs), this study used melamine particles (MP) as PBX substitutes, with graphene nanosheets (GNPs) as thermal fillers and fluorinated polymer (F2314) as the binder. The MP@GNPs core–shell structure was initially constructed using the electrostatic self-assembly method. Subsequently, the MP@GNPs/F2314 core–shell structure was fabricated via the water suspension method, and a three-dimensional thermally conductive network was established through hot pressing. At 0.5 wt% GNPs, the composite’s thermal conductivity (k) increased by 79% compared to pure MP. Further validation using HMX-based PBXs showed a 47% improvement (0.5367 W·m−1·K−1). The temperature gradient and distribution of thermal stress in PBX cylinders under complex thermal variation were evaluated using finite element analysis.
期刊介绍：
Colloid and Polymer Science - a leading international journal of longstanding tradition - is devoted to colloid and polymer science and its interdisciplinary interactions. As such, it responds to a demand which has lost none of its actuality as revealed in the trends of contemporary materials science.
