“…Although LISR have been generated by long laser pulses [37], the advancement of FS lasers has revealed exciting ways to create such structures with improved spatial resolution. LISR have found applications in creating different structural colors [9,38] and anti-reflecting coatings [4,7] and in controlling surface wetting properties [39].…”

Femtosecond (FS) laser-induced surface structuring is a robust, maskless, non-contact, and single-step process for producing micro- and nanoscale structures on a material’s surface, which remarkably alters the optical, chemical, wetting, and tribological properties of that material. Wettability control, in particular, is of high significance in various applications, including self-cleaning, anti-fouling, anti-icing, anti-corrosion, and, recently, oil–water separation. Due to growing energy demands and rapid industrialization, oil spill accidents and organic industrial discharges frequently take place. This poses an imminent threat to the environment and has adverse effects on the economy and the ecosystem. Oil–water separation and oil waste management require mechanically robust, durable, low-cost, and highly efficient oil–water manipulation systems. To address this challenge superhydrophobic–superoleophilic and superhydrophilic–underwater superoleophobic membrane filters have shown promising results. However, the recyclability and durability issues of such filters are limiting factors in their industrial application, as well as in their use in oil spill accidents. In this article, we review and discuss the recent progress in the application of FS laser surface structuring in producing durable and robust oil–water separation membrane filters. The wide variety of surface structures produced by FS laser nano- and micromachining are initially presented here, while the excellent wetting characteristics shown by specific femtosecond-induced structures are demonstrated. Subsequently, the working principles of oil–water separation membranes are elaborated, and the most recent advances in the topic are analyzed and discussed.

“…These structures offer the opportunity of controlling the optical, chemical, electrical and mechanical properties of surfaces. For this reason, LIPSS have been proposed to be used in photonics, plasmonics, or even industrial applications such as micromachining, color marking, micro fluidic technologies and micro electromechanical systems [5][6][7]. Bismuth (Bi) is a very interesting material not only due to its thermal and electrical attributes, but also because of the optical properties of its nanostructured form [8,9].…”

The formation of laser-induced periodic surface structures (LIPSS) on a bismuth thin film with a femtosecond laser is reported for the first time. The surface structures were generated at normal incidence in air environment with fluence below the ablation threshold. The effect of the number of pulses on the LIPSS morphology and on their chemical composition was investigated. The results show the generation of low spatial frequency LIPSS (LSFL), accompanied by regularly distributed nanoparticles. The LIPSS are oriented perpendicular to the laser polarization with a period ΛLSFL that doesn't show a significant variation with the number of pulses (∼1µm). In contrast to previous studies for LIPSS formation on bismuth films under ns laser irradiation [Opt. Mater. Express, 7(6), 1777-1786 (2017)], in the present case no oxidation was observed.

“…Both laser-induced surface morphologies, LIPSS and LBIA, can be generated in a single-step process and provide multiple possibilities to modify different surfaces properties. Possible applications of this laser surface texturing methods involve colorization due to diffraction at the periodic structures [14,15], modification of surface wetting properties [16,17], influence on surface cell growth [18,19], and friction management [20][21][22]. The friction properties of surfaces depend not only on the specific material and several properties of the sliding surface itself, but also on the properties of the counter body, the sliding speed, the environmental conditions, and the nature of any lubricant.…”

In this contribution we report on the possibilities of dry and lubricated friction modification introduced by different laser surface texturing methods. We compare the potential of Laser-Induced Periodic Surface Structures and Laser Beam Interference Ablation on 100Cr6 steel in a linear reciprocating ball-on-disc configuration using 100Cr6 steel and tungsten carbide balls with load forces between 50 mN and 1000 mN. For dry friction, we find a possibility to reduce the coefficient of friction and we observe a pronounced direction dependency for surfaces fabricated by Laser Beam Interference Ablation. Furthermore, Laser-Induced Periodic Surface Structures result in a load-dependent friction reduction for lubricated linear reciprocating movements. This work helps to identify the modification behaviour of laser generated micro structures with feature sizes of approximately 1 µm and reveals new possibilities for surface engineering.
