双刚性共轭嵌段共聚物体系的自组装

Self-assembly of rod-rod conjugated block copolymer

棒杆-棒杆(rod-rod)共轭嵌段共聚物体系是近几年发展起来的一类新型共轭聚合物材料,由于其特有的电学活性以及通过自组装实现纳米尺度结构可控等特性正逐渐成为人们研究的热点.构筑单元的刚性棒状结构使得rod-rod共轭嵌段共聚物体系倾向于自组装形成囊泡或层状结构等低曲率聚集体.本文总结了近年来关于rod-rod共轭嵌段共聚物体系自组装行为的研究,分别介绍了溶液中以及薄膜状态下双刚性共轭嵌段共聚物体系的自组装行为,在此基础上进一步讨论了rod-rod共轭嵌段共聚物薄膜结构与性能的关系.

All-conjugated block copolymers of the rod-rod type has been developed into a new kind of conjugated polymer materials in recent years,and came into the focus of interest because of their unique and attractive combination of electronic activity and controllable nanostructure formation.Based on their rigid-rod structure,rod-rod block copolymers show a preferred tendency to self-assemble into low-curvature vesicular or lamellar nanostructures.In this article the self-assembly properties of rod-rod conjugated block copolymer material was reviewed,including the self-assembly in solution and the solid state,and the relationship between morphologies of the conjugated block copolymer thin films and properties.
