液晶嵌段共聚物液相自组装体的结构调控

Structure Control of Liquid Crystalline Block Copolymers in Liquid-Phase Self-assembly

液晶化作用可作为一种外加驱动力,引入嵌段共聚物自组装体系中用以调控聚集体形成各向异性形貌。主链型液晶高分子刚性强,聚合难度大,而侧链型液晶高分子柔性间隔基可调,且适用于活性聚合,故侧链型液晶高分子嵌段共聚物的自组装行为获得了广泛的关注。本综述结合嵌段共聚物的液相自组装方法,从液晶基元种类、液晶相态以及功能化等方面总结了近年来侧链型液晶高分子嵌段共聚物溶液自组装体结构调控的研究与动态。最后,本综述总结了近年侧链型液晶高分子嵌段共聚物自组装相关研究工作的进展,并对其发展趋势进行了展望。

Liquid crystallization can be used as an external driving force to be introduced into the block copolymer self-assembly system to control the anisotropic morphology of the aggregates.The main chain type liquid crystalline has strong rigidity,so the polymerization is difficult.But the flexible spacer of the side-chain liquid crystalline is adjustable,and is suitable for living polymerization,so the self-assembly behavior of the side chain type liquid crystalline block copolymer has received extensive attention.In this review,combined with the liquid-phase self-assembly method of block copolymer aggregates,we summarize the research on the structure control of the side-chain liquid crystalline block copolymer solution self-assembly from the aspects of liquid crystalline mesogenic types,liquid crystalline phases state and their functionalizations.Finally,this review summarizes the limitations of the research work related to the self-assembly of side-chain liquid crystalline block copolymers,and looks forward to its development trends.
