摘要
9种咪唑二氰胺类离子液体被合成和表征,其生成焓值和比冲通过软件模拟和理论计算得到,点火延迟时间通过滴落测试由高速摄像机来判定。结果表明:1-烯丙基-3-甲基咪唑二氰胺离子液体具有最短的点火延迟时间25 ms和最低的粘度13.8 c P;1-烯丙基-3-乙烯基咪唑二氰胺离子液体具有最高的生成焓值为485 k J/mol。所有合成的离子液体均具有较宽的液态范围,密度均超过1g/ml,分解温度均超过230℃。研究发现阳离子取代基与离子液体物性和自燃燃烧性能间存在一定的规律关系,离子液体的组成以及阳离子取代基链长和饱和度对点火延迟时间和比冲有较大影响。此研究为自燃型高能离子液体的设计提供了一定的策略和参考。
