Using poly(acrylic acid)-b-poly(methyl acrylate)-b-polystyrene (PAA-b-PMA-b-PS) triblock copolymers or a mixture of different molecular weight PAA-b-PS diblock copolymers, stacks of polymeric micellar assemblies, such as disks and Y-shaped cylinders, were formed through intermicellar interactions. Whereas micelles hierarchically stacked together, micellar interactions within the stack defined a uniform micelle geometry and size for up to micrometers in length. The kinetic pathway dependence and stability of the stacked assemblies were studied, and possible intermicellar interactions between micelles within the stacks are proposed.
使用聚（丙烯酸）-b-聚（甲基丙烯酸甲酯）-b-聚苯乙烯（PAA-b-PMA-b-PS）三嵌段共聚物或不同分子量的PAA-b-PS二嵌段共聚物的混合物，通过胶束间相互作用形成了聚合物胶束聚集体的堆叠结构，如盘状和Y形圆柱体。当胶束分层堆叠在一起时，堆叠结构内的胶束相互作用定义了长达微米级的均匀胶束几何形状和尺寸。研究了堆叠聚集体的动力学途径依赖性和稳定性，并提出了堆叠结构内胶束之间可能存在的胶束间相互作用。
