利用耗散粒子动力学模拟方法,研究了由拉胀聚合物聚4'''-酰胺基对四联苯-2,6-二甲酰对苯二胺(A)与聚氧乙烯(PEO)组成的OAO形三元嵌段共聚物在溶剂N、N-二甲基甲酰胺(DMF)中的自组装行为,探究了共聚物浓度和链段A的长度对三元嵌段共聚物自组装结构的影响.结果表明,由聚4'''-酰胺基对四联苯-2,6-二甲酰对苯二胺(A)与聚氧乙烯(PEO)构筑的线型嵌段共聚物在溶剂N、N-二甲基甲酰胺(DMF)中的自组装将形成形态各异的球状、柱状、毛刷型以及"球刺"状胶束等结构;随着共聚物浓度的增加,球状胶束结构消失,逐渐演变为柱状以及毛刷型结构;随着链段A长度的增加,共聚物形成的球状胶束结构慢慢转变为"球刺"状胶束...

Dissipative particle dynamics(DPD)simulation was employed to examine the self-assembly behavior of linear triblock copolymers which are constructed of poly(ethylene oxide) (PEO) and Poly (p-phenylenediamine-4'''-aminocarbonyl-alt-2,6-diformyl quaterphenyl) (A) in N,N-Dimethylformamide (DMF).In this paper, we focused on the relationships between the evolution of self-assembly structure of those copolymers in DMF with increasing of the concentration of copolymers and the length of block A ,respectively.Simulations show that the self-assembly of those linear block copolymers in DMF can form vario...
