| 摘 要： | 采用Monte Carlo模拟方法研究了ABA两亲性三嵌段共聚物在两种选择性溶剂中的自组装行为.模拟结果表明,在保证溶剂总浓度一定的情况下,改变两种选择性溶剂的体积比对于ABA两亲性嵌段共聚物自组装所形成的胶束形貌结构有很大影响.随着双选择性溶剂体积比的改变,体系中胶束形貌结构将会发生由囊泡到层状,再到环状、棒状直至球... |

| Abstract: | The effect of binary block-selective solvents on the self-assembly of ABA amphiphilic triblock copolymer in dilute solution was studied by means of Monte Carlo study.The simulative results showed that the proportion of the binary block-selective solvents is one of the key factors that determines the morpholo-gies of the copolymer aggregates.The morphologies formed by ABA amphiphilic triblock copolymers changed from vesicle to lamella,ring,rod,and then to spheres by changing the proportion of binary solvent ... |
