合成了一种侧链型液晶单体4-(4'-烯丙氧基)苯甲酰氧基联苯单酯,将不同含量的CNT接枝到侧链液晶单体上,然后液晶单体发生聚合反应生成液晶复合材料。采用偏光显微镜(POM)、扫描电子显微镜(SEM)、差示扫描量热仪(DSC)等考察了碳纳米管的分散排列情况以及复合材料的热性能,测试结果显示,少量的碳纳米管能够较好地分散在复合材料基体中；DSC结果显示,CNT的引入提高了复合材料的清亮点,增加了液晶区间。

A side-chain liquid crystal 4-allyloxybenzoyl-4 '-hydroxyl-p-biphenyl ester (M)was synthesized using an in-situ polymerization method.Then we grafted different amounts of carbon nanotubes (CNTs ) onto it.A series of liquid crystalline polymers generated liquid crystal composite materials because of polymerization reaction.The liquid crystalline composites were characterized by polarized optical microscopy,scanning electron microscopy and differential scanning calorimetry (DSC).The results show that a little CNTs are well dispersed in the liquid crystalline composites matrix,and they cannot change the texture of the original polymer.The DSC results show that the clear point and mesomorphic temperature range increase with the adding of CNTs .
