The self-assembled microstructures of amphiphilic block copolymers depend on the selectivity of solvents for each block. By changing the selectivity of solvents, defined in terms of the repulsive interactions between the solvent and the hydrophilic/hydrophobic particles, an extensive simulation study on the spontaneous formation of complex micelles from amphiphilic triblock copolymers in a dilute solution is presented. The dynamic pathways in the formation of these assemblies have been investigated using a particle-based dissipative particle dynamics approach. In addition, the potential mechanism behind the formation of these microstructures has also been studied, which may be helpful in explaining how these aggregates are formed and in understanding the general principle of amphiphilic molecules.
两亲性嵌段共聚物的自组装微结构取决于溶剂对每个嵌段的选择性。通过改变溶剂的选择性（用溶剂与亲水/疏水粒子之间的排斥相互作用来定义），本文对两亲性三嵌段共聚物在稀溶液中自发形成复杂胶束的过程进行了广泛的模拟研究。采用基于粒子的耗散粒子动力学方法研究了这些组装体形成的动态途径。此外，还研究了形成这些微观结构的潜在机制，这可能有助于解释这些聚集体是如何形成的，并理解两亲分子的一般原理。
