Abstract Iodine oxides are of significant interest as strong oxidizers in energetic formulation that also operate as iodine release agents for neutralization of spores using strong thermal pulses. In this paper incorporation of carbon black (CB) as the main fuel or additive into iodine oxides-based energetic materials are shown to lower both initiation and iodine release temperatures compared to those of Al/iodine oxides and Ta/iodine oxides thermites. Those lowering effects were triggered by a condensed phase CB-iodine oxides reaction explored by high heating rate time-resolved temperature-jump time-of-flight mass spectrometry and low heating rate thermogravimetric analysis/differential scanning calorimetry results. We observe that other carbon allotropes, such as carbon nanotubes and functionalized graphene sheets, also feature the similar effect as CB. Fourier transform infrared spectroscopy analysis shows that the presence of CB lowered the bond energy of iodine oxide on the surface to trigger the CB-iodine oxide initiation at a relatively lower temperature.

添加碳可降低基于氧化碘的杀生物含能材料的引发和碘释放温度

摘要 碘氧化物作为高能制剂中的强氧化剂具有重要意义，它也可作为碘释放剂使用强热脉冲中和孢子。在本文中，与铝/碘氧化物和 Ta/碘氧化物铝热剂相比，将炭黑 (CB) 作为主要燃料或添加剂加入基于氧化碘的高能材料中，可以降低引发温度和碘释放温度。这些降低效应是由通过高加热速率时间分辨温度跳跃飞行时间质谱和低加热速率热重分析/差示扫描量热法结果探索的凝聚相 CB-碘氧化物反应触发的。我们观察到其他碳同素异形体，例如碳纳米管和功能化石墨烯片，还具有与CB类似的效果。傅里叶变换红外光谱分析表明，CB的存在降低了表面氧化碘的键能，从而在相对较低的温度下引发了CB-氧化碘的引发。
