含弯曲液晶基元的甲壳型液晶高分子二嵌段共聚物的合成与相结构研究
Synthesis and Phase Structures of Bent-Core Mesogen-Jacketed Liquid Crystalline Diblock Copolymers
用原子转移自由基聚合方法,合成了一系列以含弯曲液晶基元的甲壳型液晶高分子为硬段,聚苯乙烯为软段的二嵌段共聚物,并表征了其结构。小角和广角X衍射研究表明,这些聚合物能够形成层状相微相分离结构,层内甲壳型液晶高分子形成六方柱状相结构,并且柱子取向方向垂直于层面,形成类似于近晶B相结构。
series of diblock copolymers with polystyrene as coil segment and bent-core mesogen-jacketed liquid crystalline polymer as rigid segment were synthesized via sequential atom transfer radical polymerization. SAXS and WAXD studies revealed that these rod-coil blocks packed together forming a layer structure, with the rod axes parallel to the lamellar normal. Within the lamellar structure, PVC14 rods packed with high hexagonal order.
