本文通过改变搅拌速率和共聚物组成，研究了剪切流场对ABC两亲共聚物在日稀选择性溶液中自组装的影响。结果显示，自组装形态强烈依赖于搅拌速率和共聚物的组成。ABC三嵌段共聚物在选择性溶剂中形成的自组装形态是剪切流场与胶团表面张力之间竞争的结果。当搅拌速率较低时，形成球形胶团；随着搅拌速率的增加，胶团形态发生转变，可形成周聚集体和柱状结构等复杂形态。

We have studied the effect of shear flow on the self-assembly of ABC amphiphilic copolymers in dilute selective solutions by changing the stirring rate and the composition of the triblock copolymer. The results revealed that the self-assembled morphology strongly depends on the stirring rate and the composition of the copolymer. The self-assembled morphology formed by the ABC triblock copolymer in selective solvent is the result of a competition between the shear flow and the interfacial tension of the micelles.
