摘要：本文研究了ABA型两亲性三嵌段共聚物在稀溶液中形成的"crew-cut"聚集体环形形态。通过原子力显微镜（AFM）和透射电子显微镜（TEM）等表征手段，观察到了独特的环形胶束聚集形貌。研究发现，嵌段共聚物的组成、溶液浓度以及溶剂性质等因素对环形结构的形成具有重要影响。提出了环形结构形成的可能机理，为理解嵌段共聚物在溶液中的自组装行为提供了新的认识。

Abstract: The ring-shaped morphology of "crew-cut" aggregates from an ABA amphiphilic triblock copolymer in a dilute solution was investigated. Atomic force microscopy (AFM) and transmission electron microscopy (TEM) were employed to characterize the unique ring-shaped micellar aggregates. The effects of copolymer composition, solution concentration, and solvent properties on the formation of ring-shaped structures were examined. A possible formation mechanism was proposed, providing new insights into the self-assembly behavior of block copolymers in solution.
