非均匀表面与水界面的粗粒化模拟

Coarse Grained Modeling of The Interface Between Water and Heterogeneous Surfaces

Adam P. Willard, David Chandler

摘要:

使用粗粒度的模型,我们研究了水的行为相邻的扩展的疏水表面与各种分数的不同大小的亲水补丁胡椒。我们研究了平均界面高度的空间依赖性,与干燥的补丁基板的溶剂密度波动,和界面波动的空间依赖性。我们发现,添加小的均匀的基板和溶剂之间的吸引力的相互作用导致的平均位置的接口是非常接近的基板。然而,界面的波动是大的和空间异质性的响应于下面的片状基板。我们讨论了这些发现的影响组装的异质表面。

英文摘要:

Using coarse grained models we investigate the behavior of water adjacent to an extended hydrophobic surface peppered with various fractions of hydrophilic patches of different sizes. We study the spatial dependence of the mean interface height, the solvent density fluctuations related to drying the patchy substrate, and the spatial dependence of interfacial fluctuations. We find that adding small uniform attractive interactions between the substrate and solvent cause the mean position of the interface to be very close to the substrate. Nevertheless, the interfacial fluctuations are large and spatially heterogeneous in response to the underlying patchy substrate. We discuss the implications of these findings to the assembly of heterogeneous surfaces.
