We have investigated, both experimentally and theoretically, the aggregation of ABA amphiphilic triblock copolymers in dilute solution. We observed a number of complex architectures having toroidal and network structures, including some novel ones. The computational analyses of these systems offer some insight into the origins of the self-assembly of these amphiphiles. The results we obtained using real-space self-consistent field theory reveal that the formation of network and toroidal structures from the block copolymers occurs as the result of the breaking of "inhomogeneous vesicles"; the observed polymorphism results from the existence of multiple metastable states.
我们通过实验和理论研究了ABA两亲性三嵌段共聚物在稀溶液中的聚集情况。我们观察到了许多具有环形和网络结构的复杂结构，包括一些新颖的结构。对这些体系的计算分析为这些两亲物自组装的起源提供了一些见解。我们使用实空间自洽场理论获得的结果表明，嵌段共聚物形成网络和环形结构是“非均匀囊泡”破裂的结果；观察到的多态性是由多个亚稳态的存在导致的。
