| 摘 要： | 采用模拟退火方法系统研究了对称两嵌段共聚物AB/均聚物A或C混合体系受限在球形纳米孔内的自组装行为.结果表明,体系的自组装结构受均聚物含量、均聚物链长、受限尺度以及A-C间相互作用强度的影响.随着均聚物含量的变化,体系可形成多种自组装结构,包括类洋葱层、笼状、类拱顶状、螺旋状、堆叠圆盘和圆环、平层、及球状结构.当A-C...

| Abstract: | Self-assembly of symmetric diblock copolymer AB/homopolymer A or C blends confined in spherical nanopores is studied by using a simulated annealing method.Three kinds of blends with different homopolymer chain lengths are investigated.Simulation results show that the self-assembly behavior of the blends depends on the content of the homopolymer,the chain length of the homopolymer,the degree of confinement(characterized by D/L0,where D is the diameter of the spherical nanopore and L0 is the period of the bul... |
