| 摘 要： | 利用耗散粒子动力学方法研究三嵌段共聚物的链构型对其在本体中自组装行为产生的影响. 通过系统调节共聚物的链构型, 得到了形态各异的嵌段共聚物相态结构, 如规则层状结构、 小尺寸相区无规堆积结构以及扭曲阶梯状结构等. 为使体系总的自由能降低, 不同链构型的嵌段共聚物会自发产生各种有序相态结构.

| Abstract: | The influence of molecular architecture of a triblock copolymer on the self-assembly morphology was investigated by dissipative particle dynamics simulation.Tuning the architecture of the triblock copolymer,we obtained different self-assembly morphologies,e.g.,ordered layered structure,small-domain disorderly-aggregated structure and distorted stage structure,etc.To reduce the system free energy as much as possible,the triblock copolymer systems with different molecular structures would spontaneously self-assemble into different ordered morphologies. |
