摘要用自洽场理论研究了两嵌段共聚物与均聚物接枝粒子的定向自组装行为。考察了A块的比例、电刷密度、颗粒数量和排列方式等四个因素。得到了不同的有序结构，并绘制了A块体积分数和电刷密度的相图。模拟结果表明，嵌段共聚物的形态对粒子数目和排列方式比较敏感。因此，可以通过增加粒子数目和调整粒子排列来控制两嵌段共聚物的自组装。通过在纳米尺度上创建有序图案，提供了技术指南。
ABSTRACT By using self-consistent field theory, the directed self-assembly of a diblock copolymer was studied with homopolymer-grafted particles. The four factors were investigated, such as the fraction of the A block, the brush density and the number and arrangement of particles. A varies ordered structures had been obtained, while a phase diagram was constructed as a function of the volume fraction of the A block and the brush density. The simulation results showed that the morphologies of the block copolymer were sensitive to the particle number and arrangement. Therefore, the self-assembly of the diblock copolymer can be controlled by increasing the particle number and by adjusting the arrangement of particles. A technique guide was provided by creating ordered patterns at the nanoscale.
