摘要
Abstract
Al/PTFE composites incorporating KNO3,Ba(NO3)2,KClO4,and Fe2O3(mass fractions:3%,12%,and 15%)were prepared via wet mixing.The effects of oxidant type,mass fraction,and heating rate on thermal decomposition behavior and reactivity were investigated using simultaneous thermal analysis(STA).The results demonstrate that oxidant addition enhances reactivity by disrupting the inert Al2O3 shell and promoting complete oxidation of carbonaceous residues.The most significant improvement was observed in Al/PTFE composites with KNO3 mass fraction of 12%,which advanced the onset decomposition temperature by 6.97%and reduced the apparent activation energy to 128.63 kJ·mol-1.Furthermore,systems with a single oxidant(Fe2O3 or nitrate)exhibited superior reactivity compared to those containing combined Fe2O3/nitrate oxidizers,suggesting a compatibility issue within the studied specific composite oxidizers.关键词
