Self-assembly behavior of the blends of AB diblock copolymers and C homopolymers in soft confinement is studied by using a simulated annealing method. Polymer solution droplets in a poor solvent environment realize the soft confinement. Several sequences of soft confinement-induced copolymer aggregates with different shapes and internal structures are predicted as functions of the size of confinement, the number ratio of AB diblock copolymers to C homopolymers, the volume fraction of blocks, the selectivity of confinement's surface, the incompatibility between blocks, and the competition between two block-homopolymer interactions. Simulation results demonstrate that those factors are able to tune the morphology of the aggregates precisely. We anticipate the rules achieved here is helpful to fabrication of polymeric particle with predesigned morphology.
通过使用模拟退火方法研究了 AB 两嵌段共聚物和 C 均聚物在软受限环境中的自组装行为。在不良溶剂环境中，聚合物溶液液滴实现了软受限。作为受限尺寸、AB 两嵌段共聚物与 C 均聚物的数量比、嵌段体积分数、受限表面选择性、嵌段间不相容性和两种嵌段-均聚物相互作用竞争的函数，预测了具有不同形状和内部结构的一系列软受限诱导共聚物聚集体。模拟结果表明，这些因素能够精确调节聚集体的形态。我们期望这里获得的规则有助于制造具有预定形态的聚合物颗粒。
