Abstract
- Aluminum (Al) fluoropolymer composites are widely used in the field of energetic materials. At present, it is a research hotspot to improve the agglomeration of nano-aluminum powder in fluoropolymer and make micro-nano-Al/fluorine rubber (F2601) composites. In this study, it was the first step to modify the surface of nano-aluminum (n-Al) powders, and then Al/F2601 composite microspheres were prepared by Pickering emulsion. The effects of oil–water ratio, solid content and fluorine–aluminum ratio on the stability of the emulsion were investigated. Al/F2601 microspheres with particle sizes of about ≤ 50 μm and different surface pores were prepared by controlling various conditions, which appeared the thermal decomposition peak between 485.5 °C and 524.9 °C. The combustion process of samples in the air was recorded by a high-speed camera, the composites with different F2601 contents burn stably and show a clear pattern of combustion velocity, and the maximum linear combustion velocity is up to 30.7 cm s−1.
