介晶间堆积规整度调控表面取向液晶弹性体的热机械驱动
Mesogen–Mesogen Registry Tunes Thermomechanical Actuation in Surface-Aligned Liquid Crystalline Elastomers
AI 导读
研究比较了间隔基长度、网络化学与化学计量比相同、仅介晶结构不同的液晶弹性体（LCE），发现介晶间堆积规整度决定热机械驱动行为。与未甲基化类似物 C6Sym 相比，甲基化介晶 C6M 形成向列相 LCE，堆积规整度降低，驱动响应更宽且温度更低。
推荐理由
通过固定间隔基与网络化学、只改介晶结构，文章把介晶堆积规整度与热机械驱动温度区间对应起来。
创新点
在间隔基、网络化学与化学计量比不变的条件下仅改变介晶结构，把介晶间堆积规整度和间距与应变-温度耦合强弱直接关联起来。
