中文摘要：
用模拟退火方法模拟了BAB型双亲三嵌段共聚物在选择性稀溶液中的自组装过程．研究了溶剂和聚合物之间的相互作用对处于稀溶液中的三嵌段共聚物聚集体形态的影响．模拟结果表明随着溶剂（S段）和疏水嵌段（B段）之间的相互作用（εBS）的增加，共聚物自组装形态依次为球状、球柱混合状、囊泡状、洋葱状．
英文摘要：
The simulated annealing method is used to study the self-assembling process of the BAB triblock copolymer in solvents selective for block A. The influence of the interactions between the solvent and the polymer on the morphology of triblock copolymer aggregates in solution is studied. It is shown that the morphology of the aggregate changes from sphere to rod, to vesicle, and to onion with increasing the interaction between solvent and the hydrophobic blocks B.
