C6F12O (perfluoro-2-methyl-3-pentanone) is a high-potential environmentally friendly substitute agent applied in fire protection, the power industry and refrigeration. Herein, a series of reactive force field molecular dynamics (ReaxFF MD) simulations is performed to investigate C6F12O pyrolysis. Six initial pyrolysis reaction pathways are determin...

Clean gas fire suppressants with high efficiency are widely applied. This paper provides a systematic review of the research advances in the novel environmentally friendly suppressant, C6F12O. Considering the principle of screening fire suppressants, the physical and chemical properties of C6F12O are presented first. Specifically, research on the m...

Aqueous zinc metal batteries (AZMBs) have shown great promise as the advanced energy storage systems. Unfortunately, the common Zn foil anodes suffer from severe Zn dendrites growth and electrolyte corrosion, leading to limited application of AZMBs. Here, we prove that the Zn dendrites formation is bound up with the processing-induced step-edge str...

Since halon fire‐extinguishing agents are forbidden to be used due to environmental concerns, it is necessary to explore new environmentally friendly fire‐extinguishing agents. Perfluorotriethylamine (N(CF2CF3)3) with good physicochemical properties is a potential substitute for halons. To evaluate its practicability as the halon substitute, the th...

The cis‐1,1,1,4,4,4‐hexafluoro‐2‐butene (DR‐2 or HFO‐1336mzz(Z)) is a novel environmentally friendly working fluid with appropriate physicochemical characteristics. The present work firstly investigated the decomposition mechanism and thermal stability of DR‐2 in a oxygen (O2)‐containing atmosphere at high temperature experimentally. The oxidative...

The cis-1,1,1,4,4,4-hexafluoro-2-butene (DR-2 or HFO-1336mzz(Z)) is a novel environmentally friendly working fluid with appropriate physicochemical characteristics. The present work firstly investigates decomposition mechanism and thermal stability of DR-2 under the atmosphere containing oxygen (O2) and high temperature experimentally. The oxidativ...

A series of thermal decomposition experiments were conducted over a temperature range of 873–1073 K to evaluate the thermal stability of 1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz(Z)) and the production of hydrogen fluoride (HF). According to the detected products and experimental phenomena, the thermal decomposition of HFO-1336mzz(Z) could be di...

Functionalized sodium bicarbonate (FSB) powder with hydrophobicity and oleophobicity may provide a new solution to the increasingly severe aircraft engine fires. A one-step way to prepare hydrophobic and oleophobic powders by gel-sol-gel method was developed. Perfluoro copolymer gels were synthesized with PFEA (2-(perfluorooctyl) ethyl acrylate), M...

The re-ignition of pool fires is a common hazard phenomenon in fire extinguishing. Dry chemicals with oleophobicity may solve this problem because powders can float on the oil surface and prevent evaporation of fuel pool. In this research, MAPP (modified ammonium polyphosphate) with superhydrophobicity, oleophobicity, and higher chemical activity i...
