我们提出了一个包含两亲嵌段共聚物作为表面活性剂的相分离二元混合物的连续介质模型。该模型是对最近关于嵌段共聚熔体的密度泛函理论的扩展，该模型在平均意义上考虑了嵌段共聚分子(表面活性剂分子)的分子结构。我们给出了该模型的计算机模拟结果，并讨论了表面活性剂的分子内结构对相分离动力学的重要贡献，这些贡献在最近使用连续描述的表面活性剂溶液的相分离模拟中通常被忽略。
We propose a continuum model for phase separating binary mixtures containing an amphiphilic block copolymer that serves as a surfactant. The model is an extension of a recent density functional theory for block copolymer melts, and the model takes the intramolecular structure of the block copolymer molecule (surfactant molecule) in an averaged sense. We show results of a computer simulation on this model, and discuss the important contributions from the intramolecular structure of the surfactant to the phase separation dynamics, which have usually been neglected in the recent simulations on the phase separation of surfactant solutions that use continuum descriptions.
