我们报告了一个广泛的模拟研究的自组装的两亲性阿坝三嵌段共聚物溶解在溶剂中选择性的中间B-嵌段。系统地研究了共聚物组成、共聚物浓度和A-溶剂相互作用对聚集体形态和形态转变的影响。模拟结果表明，丰富多样的聚集体，从球形和棒状胶束和囊泡，环形和网笼胶束，可以自发地形成从一个随机产生的初始状态。构建了相图，并预测了丰富的形态转变。研究了不同胶束中的链堆积。模拟结果进行了比较与以前的观察或预测相关的共聚物系统。
We report an extensive simulation study of the self-assembly of amphiphilic ABA triblock copolymers dissolved in solvents selective for the middle B-block. The effects of copolymer composition, copolymer concentration, and A-solvent interactions on the morphologies and morphological transitions of the aggregates are examined systematically. The simulations reveal that a rich variety of aggregates, ranging from spherical and rodlike micelles and vesicles to toroidal and net-cage micelles, can be formed spontaneously from a randomly generated initial state. Phase diagrams are constructed and rich morphological transitions are predicted. Chain packing in different micelles is investigated. The simulation results are compared with previous observations or predictions for related copolymer systems.
