| 摘 要： | 采用耗散粒子动力学（DPD）模拟方法对两嵌段共聚物AmBn在本体和溶液中的自组装行为进行了研究．在本体情况下，对环形和线形两嵌段共聚物AmBn的相行为进行了系统的对比分析，观察了体系的有序一无序相转变规律，以及具体构型的相周期．在亲B选择性溶剂情况下，保持体系的浓度不变，改变环形两嵌段共聚物的链长，观察到了一系列丰富的相结构，有球状、圆盘状、片状、空心柱状、空心球状等．

| Abstract: | The dissipative particle dynamics（DPD） simulation method are used to study the self-assembly of diblock copolymer（AmBn） in melts and in selective solutions. For bulk case, the phase behaviors of cyclic and linear diblock copolymer are compared systematically. The order-disorder transition and the period size of a special phase are observed. In the case of B selective solution varying in the chain length of cyclic diblock copolymer, some diverse morphologies are observed, such as sphere, discoid, sheet, hollow cylinder and hollow sphere. |
