| 摘 要： | 采用Monte Carlo方法结合退火方法研究掺杂非对称两嵌段共聚物薄膜的相分离情况.发现随着掺杂极性粒子浓度的增加,嵌段共聚物薄膜体系由层状相逐渐转化成层状和柱状共混相,最后变成分布均匀的柱状相.当掺杂浓度增加到一定程度时,形成了如六边形(6-fold)、七边形(7-fold)和五边形柱状(5-fold)的相结构;六边形柱状相结构的比例随着浓度增加而增加,七边形(7-fold)和五边形柱状(5-fold)相结构的比例随着浓度增加而减小.同时还讨论了两嵌段共聚物大小与掺杂浓度的关系. |

| Abstract: | Monte Carlo method with annealing method was applied to study the diblock copolymer(A_ 10 B_6)confined thin films with different volumes of nanoparticles.When the volume of nanoparticles increases,the morphology of diblock copolymer films changes from lamellaes to the mixture of lamellae and cylinder,and finally form the cylinders.Nanoparticles localized within one copolymer block phase.When the volume of nanoparticles are large enough,the 5-,6-and 7-fold cylinder morphologies are formed,and the percentage ... |
