摘　　要：采用Monte Carlo模拟方法研究了嵌段共聚物ABA/均聚物B共混体系在选择性溶剂中的自组装行为.模拟结果表明,在保证高分子浓度一定的情况下,改变均聚物的含量对于自组装所形成的胶束形貌结构有很大影响.当均聚物含量增大到一定程度,体系最终得到大的球状胶束.The self - assembly of triblock copolymer ABA/homopolymer B blends in block - selective sol- vents was studied by means of Monte Carlo method. The simulative results showed that the volume fraction of the homopolymer is one of the key factors that determines the aggregate morphologies. The morphologies changed to large spherical aggregates by increasing the volume fraction of the homopolymer.
