摘要：
The aggregated properties of the amphiphilic polystyrene (PS)/poly(4-vinypyridine) (P4VP) triblock copolymer in a dioxane/water mixture were investigated. The morphologies of the aggregates were studied using transmission electron microscopy (TEM) and atomic force microscopy (AFM). It was observed that the morphology of the copolymer was changed from rod-shaped structure to ring-shaped structure with increasing annealing time. The results from AFM and TEM show that ring shape is the dominant morphology of the aggregates.
