Synthesis and Fire Suppression Performance of Thermosensitive Microelncapsulated Cis‐Hexafluoro‐2‐Butene

ABSTRACT Confined‐space electrical fires present significant hazards, primarily stemming from the inherent limitations of conventional fire‐extinguishing agents. To address this challenge, thermosensitive microencapsulated cis‐hexafluoro‐2‐butene (HFO‐1336mzz(Z)) fire extinguishing agents were synthesized via microfluidic technology, using melamine resin as the shell material and HFO‐1336mzz(Z) as the composite core. The microcapsules featured uniform particle size and smooth, dense surfaces morphologies. Furthermore, the release behavior and fire extinguishing efficiency of the microcapsules were systematically analyzed. Key findings are summarized as follows: The pyrolysis of the microcapsules proceeds…
