Benzotrioxofurazan (BTF) -based composite explosives containing three different binder components were prepared in this study, using nitrocellulose (NC), thermoplastic polyurethane (Estane), and fluororubber 2602 (F₂₆₀₂) as binders, through the electrostatic spray method. The objective was to reduce the sensitivity of BTF. The BTF-based composite explosives were characterised using a range of scientific equipment, including scanning electron microscopy (SEM), Fourier Transform infrared spectroscopy (FT-IR), DSC thermal analysis, and mechanical sensitivity. The SEM results indicated that the BTF-based composite explosives’ particle size was between 50 and 100 nm, and had a spherical shape. Compared with the raw BTF, the critical temperature of thermal explosion of the three composite explosives, BTF/NC, BTF/Estane and BTF/F₂₆₀₂, was increased by 4.21, 6.8 and 9.44 °C, respectively. These increases indicate an improvement in the thermal stability of the samples. The characteristic drop height of BTF/NC, BTF/Estane and BTF/F₂₆₀₂ was 68.12, 62.34 and >80 cm, respectively. Additionally, the explosion percentage of BTF/NC, BTF/Estane and BTF/F₂₆₀₂ had been decreased to 24%, 24%, and 8%, respectively. These results suggest a significant enhancement in the safety performance of all three samples.
