We propose a general method for predicting shapes of fluid vesicles with anchored polymers. The method combines the Helfrich curvature elasticity theory for fluid membranes and the self-consistent field theory for polymers, to determine stable and metastable shapes of the vesicles as well as the segment distributions of the anchored chains. We illustrate the method by investigating the shape change of a fluid vesicle induced by a single anchoring polymer chain. Extension to more complicated systems, such as vesicles with multiple anchored chains, block copolymers, or semiflexible chains, is straightforward.
我们提出了一种预测带有锚定聚合物的流体囊泡形状的通用方法。该方法将用于流体膜的赫尔弗里希曲率弹性理论与用于聚合物的自洽场理论相结合，以确定囊泡的稳定和亚稳形状以及锚定链的链段分布。我们通过研究单个锚定聚合物链引起的流体囊泡形状变化来说明该方法。将其扩展到更复杂的系统，如具有多个锚定链的囊泡、嵌段共聚物或半柔性链，是很直接的。
