“…Chen et al [ 11 ] produced a reed-leaf-like (superhydrophobic stainless surface with the WCA of 157 ± 1° and WRA of 1.0 ± 0.5° by using nanosecond laser irradiation, and it exhibited good corrosion resistance. Yang et al [ 12 ] found that the laser-fabricated aluminum superhydrophobic surface with the WCA of 160.6 ± 1.5° and WRA of 3 ± 1° exhibited perfect self-cleaning capability, long-term stability, and excellent chemical stability in acidic as well as alkaline solutions. Fadeeva et al [ 13 ] reported that the laser-produced superhydrophobic Ti surface with the WCA of 166 ± 4° exhibited good antibacterial property.…”

Laser irradiation is a popular method to produce microtextures on metal surfaces. However, the common laser-produced microtextures were hierarchical (multiscale), which may limit their applicability. In this paper, a method of two-step laser irradiation, combining first-step strong ablation and sequentially second-step gentle ablation, was presented to produce micron-rough surface with single-scale microtextures. The effect of laser fluence on the Ti–6Al–4V surface morphology and wettability were investigated in detail. The morphology results revealed that the microtextures produced using this method gradually evolved from multiscale to single-scale meanwhile from microprotrusions to microholes with increasing the second-step laser fluence from 0.0 to 2.4 J/cm2. The wettability and EDS/XPS results indicated that attributing to the rich TiO2 content and micron roughness produced by laser irradiation, all the two-step laser-irradiated surfaces exhibited superhydrophilicity. In addition, after silanization, all these superhydrophilic surfaces immediately turned to be superhydrophobic with close water contact angles of 155–162°. However, due to the absence of nanotextures, the water-rolling angle on the superhydrophobic surfaces with single-scale microtextures distinctly larger than those with multiscale ones. Finally, using the two-step laser-irradiation method and assisted with silanization, multifunctional superhydrophobic Ti–6Al–4V surfaces were achieved, including self-cleaning, guiding of the water-rolling direction and anisotropic water-rolling angles (like the rice-leaf), etc.

“…Inspired by natural lotus leaves [ 2 ], rose petals [ 3 ], and butterfly wings [ 4 ], super-hydrophobic surfaces (i.e., apparent contact angle above 150° and sliding angle below 10°) have been successfully mimicked through the synergetic effects of micro/nanostructure fabrication and surface chemical modification [ 5 , 6 , 7 , 8 , 9 , 10 ]. Due to their enormous potential applications including anti-icing [ 11 ], drag reduction [ 12 ], self-cleaning [ 13 ], anti-bacteria [ 14 ], and corrosion resistance [ 15 ], super-hydrophobic surface mimicry has been extensively developed by state-of-the-art techniques, such as thermal imprinting [ 16 , 17 ], chemical vapor deposition [ 18 ], coating [ 19 ], electrochemical deposition [ 20 , 21 ], and laser texturing [ 22 , 23 , 24 , 25 , 26 , 27 ]. Particularly, laser texturing can be seen as one of the facile approaches, and therefore can be extensively utilized to fabricate super-hydrophobic substrates owing to its precise control of surface fabrication with three dimensional (3D) hierarchical structures [ 28 ].…”

A super-hydrophobic aluminum alloy surface with decorated pillar arrays was obtained by hybrid laser ablation and further silanization process. The as-prepared surface showed a high apparent contact angle of 158.2 ± 2.0° and low sliding angle of 3 ± 1°. Surface morphologies and surface chemistry were explored to obtain insights into the generation process of super-hydrophobicity. The main objective of this current work is to investigate the maximum spreading factor of water droplets impacting on the pillar-patterned super-hydrophobic surface based on the energy conservation concept. Although many previous studies have investigated the droplet impacting behavior on flat solid surfaces, the empirical models were proposed based on a few parameters including the Reynolds number (Re), Weber number (We), as well as the Ohnesorge number (Oh). This resulted in limitations for the super-hydrophobic surfaces due to the ignorance of the geometrical parameters of the pillars and viscous energy dissipation for liquid flow within the pillar arrays. In this paper, the maximum spreading factor was deduced from the perspective of energy balance, and the predicted results were in good agreement with our experimental results with a mean error of 4.99% and standard deviation of 0.10.

“…In addition, the C-Si bond was also detected locating at the 283.9 eV [39]. The detected fluoride functional groups were definitely originated from the FAS molecules, resulting in the formation of super-hydrophobicity for the laser-induced surface due to the dramatic reduction of surface free energy [40].…”
