Orientational Order of Molecular Assemblies on Rough Surfaces

Abstract: Using atomic force microscopy, we show that previous observations on the orientational order of micelles on atomically smooth crystals with directions dictated by the crystal symmetry is only valid for the case of perfectly smooth crystals. On rough surfaces, orientations are independent of the lattice symmetry and the observed directions can be explained by considering the guiding influence of topographic surface features.

“…13,14,76 This would correspond to a monolayer formed of columns of lipids opposing each other. The lipids adopting a side-by-side structure in our simulations is likely a concentration dependent phenomenon (opposing lipid morphology induced only upon further adsorption) and also possibly influenced by the finite size of the simulations box.…”

“…23 Schniepp et al showed that the orientation of sodium dodecylsulfate (SDS) surfactants on Au(111) surfaces strongly depends on surface roughness. 24,25 Wu et al reported that surface roughness affects the amount of cetyltrimethylammonium bromide (CTAB) surfactant adsorbed on gold, as well as the visco-elastic properties of the self-assembled aggregates. 26 From a theory and simulation point of view, a few authors addressed the adsorption of surfactants on heterogeneous surfaces.…”

“…Although the work performed by Lipkowski's group has extended over a variety of surfactant headgroups and chain lengths, to date the role of the surface crystallography has largely been ignored. Aksay has investigated the role of the crystal symmetry and roughness on the orientational order of sodium dodecyl sulfate (SDS) surface micelles [24,25] but there is no thermodynamic data available for surfactant adsorption on other low index surfaces such as Au(1 1 0) or Au(1 0 0).…”
