HYPOTHESIS Weakly bound, physisorbed hydrocarbons could in principle provide a similar water-repellency as obtained by chemisorption of strongly bound hydrophobic molecules at surfaces. EXPERIMENTS Here we present experiments and computer simulations on the wetting behaviour of water on molecularly thin, self-assembled alkane carpets of dotriacontane (n-C32H66 or C32) physisorbed on the hydrophilic native oxide layer of silicon surfaces during dip-coating from a binary alkane solution.

Water Nanodroplet on a Hydrocarbon "Carpet"-The Mechanism of Water Contact Angle Stabilization by Airborne Contaminations on Graphene, Au, and PTFE Surfaces.
TLDR
It is shown, in contrast to commonly approved opinion, that adsorbed hydrocarbons can increase (graphene, Au) or decrease (PTFE) the WCA of a nanodroplet sitting on a surface. Expand
Spontaneous formation of nanopatterns in velocity-dependent dip-coated organic films: from dragonflies to stripes.
TLDR
The stripes' strong crystalline texture and the well-defined separation are due to an anisotropic 2D crystallization in narrow liquid fingers, which result from a Marangoni flow driven hydrodynamic instability in the evaporating dip-coated films, akin to the tears of wine phenomenology. Expand
High-resolution ellipsometric study of an n-alkane film, dotriacontane, adsorbed on a SiO2 surface
Using high-resolution ellipsometry and stray light intensity measurements, we have investigated during successive heating-cooling cycles the optical thickness and surface roughness of thinExpand
Self‐assembled silane monolayers: an efficient step‐by‐step recipe for high‐quality, low energy surfaces
Organosilane self-assembled monolayers (SAMs) are commonly used for modifying a wide range of substrates. Depending on the end group, highly hydrophobic or hydrophilic surfaces can be achieved.Expand
Bioinspired self-repairing slippery surfaces with pressure-stable omniphobicity
TLDR
A strategy to create self-healing, slippery liquid-infused porous surface(s) (SLIPS) with exceptional liquid- and ice-repellency, pressure stability and enhanced optical transparency, applicable to various inexpensive, low-surface-energy structured materials (such as porous Teflon membrane). Expand
How Water Advances on Superhydrophobic Surfaces.
TLDR
It is proposed that the apparent receding contact angle should be used for characterizing superliquid-repellent surfaces rather than the apparent advancing contact angle and hysteresis. Expand
Atomic force microscopy measurements of topography and friction on dotriacontane films adsorbed on a SiO2 surface.
TLDR
The lateral friction is sensitive to the molecular orientation in the underlying crystalline film and can be used effectively with topographic measurements to resolve uncertainties in the film structure. Expand
Emerging applications of superhydrophilic-superhydrophobic micropatterns.
TLDR
The methods for fabricating superhydrophilic-superhydrophobic patterns are described and some of the newer and emerging applications of these patterned substrates that are currently being explored are highlighted. Expand
Wetting of silica by n-alkanes
The thicknesses of a series of n-alkane liquid films on the surface of vitreous silica were measured at a low disjoining pressure using ellipsometry. Whereas pentane, hexane and heptane wet theExpand
Morphology of air nanobubbles trapped at hydrophobic nanopatterned surfaces.
TLDR
Transmission small-angle X-ray scattering measurements show stable trapping of air inside the cavities with a partial water penetration of 5-10 nm into the pores, independent of their large depth variation. Expand
