ed ionic liquids (ILs) with properties and performances comparable to hydrazine derivatives were designed and synthesized. These new ILs as bipropellant fuels, have some unique advantages including negligible vapor pressure, ultra‐short ignition delay (ID) time, and reduced synthetic and storage costs, thereby showing great application potential as environmentally friendly fuels in bipropellant formulations
在推进剂系统中,最常见的双推进剂由两种化学物质组成:燃料(或还原剂)和氧化剂。目前,推进剂燃料的选择主要取决于肼及其甲基化衍生物,尽管它们毒性极高,挥发性高,对绝热压缩敏感(有爆炸的危险),因此难以处理。在这种背景下,寻找替代绿色推进剂燃料一直是空间科学的紧迫目标。在这项研究中,设计并合成了一个新的基于氰基硼氢化物的离子液体(ILs)系列,其性质和性能可与肼衍生物媲美。这些新型的IL作为双推进剂燃料,具有一些独特的优势,包括可忽略的蒸气压,超短点火延迟(ID)时间以及降低的合成和存储成本,
