采用同轴圆筒剪切仪和透射电子显微镜研究了剪切流场对两亲性PS-b-P2VP-b-PEO三嵌段共聚物在选择性溶剂中自组装形成多节状蠕虫胶束的影响。结果表明，剪切流场对蠕虫状胶束的形态有显著影响，多节状蠕虫胶束的形成是剪切力与界面张力共同作用的结果。通过调节剪切速率，可以控制蠕虫胶束的节状结构和长度。

Effect of shear flow on the formation of multicompartment wormlike micelles of PS-b-P2VP-b-PEO triblock copolymer in selective solvent was studied using a coaxial cylinder shear apparatus and transmission electron microscopy. Results showed that shear flow significantly affects the morphology of wormlike micelles. The formation of multi-junction wormlike micelles results from the competition between shear force and interfacial tension.
