论文摘要
胶体膜,像分子一样对齐杆的自组装单层,为设计具有确定形状和曲率的膜的模板提供了模板,未来可能是新功能。通常,组成杆由于其分子性手性,相对于膜法线会倾斜。这种倾斜在弯曲膜上的空间模式是由于耗尽力之间的竞争,列不相互作用,分子手性和边界效应引起的。我们提出了一种在最小表面(例如螺旋型和链球菌)上的倾斜模式的协变理论,该理论直到最近才在实验室中产生。我们预测了几种不均匀的倾斜模式,其中一些与实验观察结果一致,有些尚未发现。
Colloidal membranes, self assembled monolayers of aligned rod like molecules, offer a template for designing membranes with definite shapes and curvature, and possibly new functionalities in the future. Often the constituent rods, due to their molecular chirality, are tilted with respect to the membrane normal. Spatial patterns of this tilt on curved membranes result from a competition among depletion forces, nematic interaction, molecular chirality and boundary effects. We present a covariant theory for the tilt pattern on minimal surfaces, like helicoids and catenoids, which have been generated in the laboratory only recently. We predict several non-uniform tilt patterns, some of which are consistent with experimental observations and some, which are yet to be discovered.
