Conventional wetting theories on rough surfaces with Wenzel, Cassie-Baxter, and Penetrate modes suggest the possibility of tuning the contact angle by adjusting the surface texture. Despite decades of intensive study, there are still many experimental results that are not well understood because conventional wetting theory, which assumes an infinite droplet size, has been used to explain measurements of finite-sized droplets. Here, we suggest a wetting theory applicable to a wide range of… 

Gravitational Effect on the Advancing and Receding Angle of a 2D Cassie-Baxter Droplet on a Textured Surface.

It is shown that the shape of a droplet smaller than the capillary length can be substantially modified by gravity under advancing and receding conditions, and the gravitational effect plays a key role on the movement of the droplet tip.

How and When the Cassie-Baxter Droplet Starts to Slide on Textured Surfaces.

A new theoretical model is proposed that can predict the sliding condition of a two-dimensional (2D) Cassie-Baxter droplet without any a priori measurement but using only the surface information and is validated against the 2D line-tension-based front-tracking method (LTM), which can seamlessly capture the attachment and detachment between the droplet and the textured surface.

Size dependent influence of contact line pinning on wetting of nano-textured/patterned silica surfaces.

The current work studied both behaviors using molecular dynamics simulation with more than 300 different size water droplets on silica surfaces with three different patterns across two different wetting conditions and found that the pinning effect is scalable with the droplets volume, not the size of the droplet base.

Apparent Contact Angle around the Periphery of a Liquid Drop on Roughened Surfaces

The effect of roughness on the effective contact angle of a water droplet on a roughened hydrophobic surface is explored and it is shown that the apparent contact angle varies around the periphery of the droplet due to the roughness of the surface on first contact.

Geometric and chemical nonuniformity may induce the stability of more than one wetting state in the same hydrophobic surface.

The main effect of disorder is to induce the stability of both wetting states on the same substrate, and the influence of the disorder on the contact angle of the droplet is negligible for the chemical disorder and for pillar-distance disorder.

Hydrophobicity evolution on rough surfaces.

It is shown that the penetrated state with a round bottom is inevitable for a droplet smaller than the micropattern-dependent critical size, revealing a more complete picture of hydrophobicity involving the partially penetrated state and its role in the wetting state transition.

Insights from molecular simulations on liquid slip over nanostructured surfaces

The current study focuses on non-equilibrium molecular dynamics (NEMD) simulations to investigate the slip properties of water flowing over different nanostructured surfaces. A simulation protocol is

Controlling the Wettability of Steel Surfaces Processed with Femtosecond Laser Pulses.

This work presents two different laser-based direct-write strategies that allow tuning the wetting properties of 1.7131 steel over a wide range of contact angles using a high repetition rate femtosecond laser and demonstrates that the structures can be easily replicated in a polymer using a laser-fabricated steel master, which enables low-cost mass production.



A theory for the morphological dependence of wetting on a physically patterned solid surface.

It is shown that contact-line pinning is important for superhydrophobicity and that the contact angle is maximized when the droplet size is comparable to the length scale of the surface pattern.

Beyond the lotus effect: roughness influences on wetting over a wide surface-energy range.

It is shown that the pinning strength of a surface is independent of the surface chemistry, provided that neither capillary forces nor air enclosure are involved.

Anisotropic wetting on tunable micro-wrinkled surfaces.

This study probes the wetting of liquids on anisotropic micro-wrinkled features that exhibit well-defined aspect ratios that can be actively tuned and finds that droplet wetting anisotropy is governed primarily by the roughness aspect ratio.

Anisotropy in the wetting of rough surfaces.

Graphene drape minimizes the pinning and hysteresis of water drops on nanotextured rough surfaces.

This work found that the ultrasheer graphene drape prevents the penetration of water into the textured surface thereby drastically reducing the contact angle hysteresis and preventing the liquid contact line from getting pinned to the substrate.

Dependence of macroscopic wetting on nanoscopic surface textures.

It is shown that texture size is the dominant parameter in determining surface hydrophobicity when the size approaches a limiting physical length scale, as defined by tau and the surface tension of the liquid.

Rough wetting

If a rough surface is put in contact with a wetting liquid, the roughness may be spontaneously invaded depending on the surface pattern and the wetting properties of the liquid. Here, we study the

Slippery Wenzel State.

The results show that the classical Wenzel eq (1936) cannot predict the wetting behaviors of highly wetting liquids in the Wenzel state, and it is shown that droplet mobility can be maintained even after the Cassie-to-Wenzel transition.

Solving the Controversy on the Wetting Transparency of Graphene

It is shown that the liquid bulk modulus is crucial to accurately calculate the van der Waals interactions between the liquid and the surface, and that various wetting states on rough surfaces must be considered to understand a wide range of contact angle measurements that cannot be fitted with a theory considering the flat surface.

Effect of roughness geometry on wetting and dewetting of rough PDMS surfaces.

All three surfaces have the same stable wetting states after vibration and that water droplets pin in the smooth area of the rough PDMS surfaces, supported by visual inspection of the contact lines before and after vibration.
