摘要：通过改变溶剂组成系统研究了ABA型两亲性三嵌段共聚物在稀溶液中可控聚集形态的变化规律。利用透射电子显微镜(TEM)和动态光散射(DLS)等手段表征了不同溶剂组成下聚集体的形貌和尺寸。研究发现，通过调节选择性溶剂的含量，可以实现聚集体从球形胶束向蠕虫状胶束、囊泡、环形结构等多种形态的可控转变。揭示了溶剂质量对嵌段共聚物自组装行为的调控机理，为复杂聚合物聚集体的可控制备提供了实验和理论依据。

Abstract: Study of controllable aggregation morphology of ABA amphiphilic triblock copolymer in dilute solution by changing the solvent composition was investigated. TEM and DLS were employed to characterize the aggregate morphologies and sizes. By adjusting the selective solvent content, controllable transitions among spherical micelles, wormlike micelles, vesicles and ring-shaped structures were achieved.
