Coarse Grained Modeling of The Interface BetweenWater and Heterogeneous Surfaces

PDF Version Also Available for Download.

Description

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 ... continued below

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.

We discuss the implications of these findings to the assembly of heterogeneous surfaces.
