两亲性嵌段共聚物的自组装结构依赖于溶剂对嵌段的选择性。通过改变溶剂的选择性，定义在溶剂和亲水/疏水粒子之间的排斥相互作用，一个广泛的模拟研究的自发形成的复杂胶束从两亲性三嵌段共聚物在稀溶液中。这些组件的形成中的动态路径已被研究使用基于粒子的耗散粒子动力学方法。此外，还研究了这些微结构形成背后的潜在机制，这可能有助于解释这些聚集体是如何形成的，并有助于理解两亲性分子的一般原理。
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.
