“…Currently, extensive attention has focused on superhydrophobic surfaces that play a significant role in various applications related to energy, resources and environment, including self-cleaning, anti-fogging, anti-corrosion, anti-icing, anti-bacteria and drag reduction [7][8][9][10][11][12][13][14][15][16][17]. Superhydrophobic surface is generally defined as a solid surface with water contact angle (WCA) exceeding 150° and rolling angle (RA) below 10° [18,35].…”

Topographic and wetting properties of Inconel 718 (IN718) surfaces were modified via nanosecond laser treatment. In order to investigate surface wetting behavior without additional post treatment, three kinds of microstructures were created on IN718 surfaces, including line pattern, grid pattern and spot pattern. From the viewpoint of surface morphology, the results show that laser ablated grooves and debris significantly altered the surface topography as well as surface roughness compared with the nontreated surfaces. The effect of laser parameters (such as laser scanning speed and laser average power) on surface features was also discussed. We have observed the treated surface of IN718 showed very high hydrophilicity just after laser treatment under ambient air condistion.And this hydrophicility property has changed rapidly to the other extreme; very high hydrophobicity over just about 20 days. Further experiments and analyses have been carried out in order to investigate this phenomena. Based on the XPS analysis, the results indicate that the change of wetting property from hydrophilic to hydrophobic over time is due to the surface chemistry modifications, especially carbon content. After the contact angles reached steady state, the maximum water contact angle (WCA) for line-patterned and grid-patterned surfaces increased to 152.3  1.2° and 156.8  1.1° with the corresponding rolling angle (RA) of 8.8  1.1° and 6.5  0.8°, respectively. These treated IN718 surfaces exhibited superhydrophobic property. However, the maximum WCA for the spot-patterned surfaces just increased to 140.8  2.8° with RA above 10°. Therefore, it is deduced that laser-inscribed modification of surface wettability has high sensitivity to surface morphology and surface chemical compositions. This work can be utilized to optimize the laser processing parameters so as to fabricate desired IN718 surfaces with hydrophobic or even superhydrophobic property and thus extend the applications of IN718 material in various fields.

“…Superoleophobicity and hierarchical topography were also observed with nanosphere stacking 22 or spray casting. 23 The methods to fabricate amphiphobic surfaces follow usually either stochastic or biomimetic bottom-up approaches [22][23][24][25][26] or microfabrication top-down approaches. 21,27,28 The latter produce ordered surfaces and are also useful for basic studies, while the former usually produce random, hierarchical surfaces presumably at a lower cost.…”

Ordered, hierarchical (triple-scale), superhydrophobic, oleophobic, superoleophobic, and amphiphilic surfaces on poly(methyl methacrylate) PMMA polymer substrates are fabricated using polystyrene (PS) microparticle colloidal lithography, followed by oxygen plasma etching-nanotexturing (for amphiphilic surfaces) and optional subsequent fluorocarbon plasma deposition (for amphiphobic surfaces). The PS colloidal microparticles were assembled by spin-coating. After etching/nanotexturing, the PMMA plates are amphiphilic and exhibit hierarchical (triple-scale) roughness with microscale ordered columns, and dual-scale (hundred nano/ten nano meter) nanoscale texture on the particles (top of the column) and on the etched PMMA surface. The spacing, diameter, height, and reentrant profile of the microcolumns are controlled with the etching process. Following the design requirements for superamphiphobic surfaces, we demonstrate enhancement of both hydrophobicity and oleophobicity as a result of hierarchical (triple-scale) and re-entrant topography. After fluorocarbon film deposition, we demonstrate superhydrophobic surfaces (contact angle for water 168°, compared to 110° for a flat surface), as well as superoleophobic surfaces (153° for diiodomethane, compared to 80° for a flat surface).

“…66 nanoparticles are the most common inorganic materials. There are three typical approaches: (1) the nanoparticles are first blended with the fluoropolymer, then the solution is coated onto the substrates; 83,85,91,93 (2) the nanoparticles are first modified with low surface energy compounds, then the modified particles are coated on the substrates; 84,88,92 (3) the nanoparticles are first stacked on the substrates, then coated with fluoropolymers. 66,86,87 Schutzius et al followed the first approach, and made dispersions by combining fluoropolymer blends with clay nanoparticles or carbon nanowhiskers.…”

The construction and application of superoleophobic surfaces have aroused worldwide interest during the past few years. These surfaces are of great significance not only for fundamental research but also for various practical applications in self-cleaning, oil-repellent coatings, and antibioadhesion. The unique properties of polymers have made them one of the most important materials for constructing superoleophobic materials. This article reviews recent developments in the design, fabrication, and application of polymeric superoleophobic surfaces.
