“…It is important to highlight the importance of the current study since it opens the possibility of integrating a PVD process and additive manufacturing technologies (as 3D printing) in order to obtain a higher performance in ceramic pieces, which is possibly applicable to other substrates. Other studies were focused in obtaining antibiofouling properties in marine applications [19,20], medical implants [21,22] or water treatments [23], until now, none has studied how to integrate aesthetic and antibiofouling properties as part of a multifunctional applied solution.…”

Additive manufacturing (AM) is a hot topic nowadays, having a first order in importance in research trends, improving existent technologies and carrying them further. AM can be applied to ceramics, which have importance in current technologies. Their capability to maintain functional properties for long time periods, combined with the easiness to process and the abundance of raw materials, make them a fundamental part of mankind development. Within ceramics, stoneware has a wide range of uses but in some conditions, it can be affected by biofouling. Ti(O)N and Ag-Ti(O)N coatings over 3D printed stoneware, were presented as multifunctional solution, linking aesthetical and antimicrobial properties. Films were developed by reactive direct current (DC) magnetron sputtering and characterized physical, chemical and morphologically, as well as regarding their colour variation. Moreover roughness, wettability, antibacterial and antibiofouling were also evaluated. The results revealed that the Ag doped coatings (with or without oxygen addition) had an enhanced multifunctionality compared to control samples (without Ag). Ag nanoparticles addition created a surface with potential antibacterial and antibiofouling activities, in order to resist outdoors and aqueous environments, making these films able to be applied in architectural pieces as sculptures or other decorative parts, maintaining their properties with good aesthetical properties. implants, soft tissue replacements, drug deliveries, among others [2]; aerospace industry, in reduced volume parts and replacements parts for aircraft with advanced materials as aluminium alloys, titanium alloys, nickel super-alloys and special steels; automotive industry, in the development of some structural and engine parts; and tooling industry, like moulds with complex refrigeration systems enabling better performances and higher life time, [3]. Additive manufacturing, namely with metals and polymers, is no longer the future, it is the unavoidable present, but the additive manufacture of ceramic materials is still far from the desired maturity. Abundance, easy manipulation, low cost, heat resistance and long life time span are the main characteristics of ceramics [4] and across human history, new technologies have enlarged its uses. Chemically, ceramics can be considered as compounds formed between metallic and non-metallic elements with predominant ionic bonding but having a

“…The polymer layer thickness was controlled by the extent of electron-induced cross-linking and head group conversion of the SAM layer [ 5 , 28 ]. In a recent study, picosecond (ps) laser texturing of stainless steel was carried out by Sun et al [ 37 ], generating micro-groove and micro-pit arrays which were tested in the laboratory in artificial seawater. The results were reported to be a fast, highly controllable picosecond laser patterning way for preparing hierarchical micro/nanostructures, combined with the chemical modification by silica sol, was proposed to fabricate the anti-biofouling stainless steel superhydrophobic surfaces (SHSs).…”

The imitation of natural systems to produce effective antifouling materials is often referred to as “biomimetics”. The world of biomimetics is a multidisciplinary one, needing careful understanding of “biological structures”, processes and principles of various organisms found in nature and based on this, designing nanodevices and nanomaterials that are of commercial interest to industry. Looking to the marine environment for bioinspired surfaces offers researchers a wealth of topographies to explore. Particular attention has been given to the evaluation of textures based on marine organisms tested in either the laboratory or the field. The findings of the review relate to the numbers of studies on textured surfaces demonstrating antifouling potential which are significant. However, many of these are only tested in the laboratory, where it is acknowledged a very different response to fouling is observed.

“…Artificial superhydrophobic surfaces play an important role in a variety of applications such as drag reduction [1], anti-biofouling [2], microfluidic manipulation [3], anti-icing [4][5][6], water collection [7], and wearable electronics [8]. For a promising superhydrophobic surface used in artificial skin and wearable electronics, high stretchability, durability, biological safety, and easy fabrication are highly desirable, so the proper selection of substrate materials and fabrication method is very crucial.…”

Highly stretchable and robust superhydrophobic surfaces have attracted tremendous interest due to their broad application prospects. In this work, silicone elastomers were chosen to fabricate superhydrophobic surfaces with femtosecond laser texturing method, and high stretchability and tunable adhesion of the superhydrophobic surfaces were demonstrated successfully. To our best knowledge, it is the first time flexible superhydrophobic surfaces with a bearable strain up to 400% are fabricated by simple laser ablation. The test also shows that the strain brings no decline of water repellency but an enhancement to the superhydrophobic surfaces. In addition, a stretching-induced transition from "petal" state to "lotus" state of the laser-textured surface was also demonstrated by non-loss transportation of liquid droplets. Our results manifest that femtosecond laser ablating silicone elastomer could be a promising way for fabricating superhydrophobic surface with distinct merits of high stretchability, tunable adhesion, robustness, and non-fluorination, which is potentially useful for microfluidics, biomedicine, and liquid repellent skin.
