AI Technical Summary
Existing technologies struggle to effectively improve the thermal conductivity and mechanical properties of mixed explosives under low filler load conditions. Furthermore, the poor interfacial compatibility between carbon nanofillers and explosive crystals and polymer binders results in high interfacial thermal resistance, leading to insufficient thermal conductivity enhancement efficiency.
Ionic liquids were used to non-covalently functionalize graphene nanosheets and carbon nanotubes. Through non-covalent interactions such as π-π stacking, cation-π interaction, and hydrogen bonding, the dispersibility and interfacial compatibility of carbon nanofillers in mixed explosives were improved, and the interfacial interactions were enhanced.
Without damaging the intrinsic thermally conductive structure of carbon nanofillers, the interfacial thermal resistance is significantly reduced, the thermal conductivity utilization efficiency is improved, and the tensile fracture strength and fracture strain of the mixed explosive are enhanced, thereby strengthening its ability to resist thermal stress damage.
