“…The mechanical properties and corrosion inhibition capability of nanoparticle-based coatings are comparable with those of other methods [73]. Another advantage of nanoparticle-based coatings is that various nanoparticles can be solely dispersed or combined in a polymer base [74][75][76][77][78][79].…”

“…It is interesting to note that this technique is capable of precise replication of overhanging hierarchical structures through atomic layer deposition. Hoshian et al replicated overhanging nanostructures from an aluminum tube template to polydimethylsiloxane and titania using atomic layer deposition sacrificial etching [74]. Atomic layer deposition of ceramics such as titania improves the mechanical durability of developed coatings considerably.…”

Engineered superhydrophobic coating for anti-corrosion applications is a subject of great significance at present. However, the use of superhydrophobic coatings for anti-corrosion applications is hindered by the mechanical durability in many cases. There is a need for an understanding not only of how to fabricate such surfaces, but also of the corrosion resistance and mechanical durability of those coatings. This review discusses recent developments in the mechanical durability of superhydrophobic coatings primarily used for anti-corrosion. First, superhydrophobicity is introduced with an emphasis on different wetting models. After that, this review classifies the nanofabrication methods based on the material and methods of surface functionalization. Furthermore, the testing procedures used for the measurement of corrosion and mechanical durability are presented. Finally, the mechanical durability and anti-corrosion performance of the developed superhydrophobic coatings are discussed.

“…The superhydrophobic surface is defined by a surface exhibiting an apparent contact angle greater than 150°, contact angle hysteresis lesser than 10°, and sliding angle lesser than 10° [ 6 , 8 ]. Contact angle is the angle depicted by water droplet at the contact line when it comes in contact with the solid surface.…”

“…Nonetheless, blood compatibility remains a long-existing challenge in developing biomaterials for blood-contacting medical devices. Significant blood-compatible biomaterials suitable for medical devices are difficult to be forged as the mechanism of adhesion of blood cells and microorganisms on the surface are complex and multifactorial [ 6 ]. Boundary condition also takes part in affecting the interaction between molecules and surface.…”

Medical devices are indispensable in the healthcare setting, ranging from diagnostic tools to therapeutic instruments, and even supporting equipment. However, these medical devices may be associated with life-threatening complications when exposed to blood. To date, medical device-related infections have been a major drawback causing high mortality. Device-induced hemolysis, albeit often neglected, results in negative impacts, including thrombotic events. Various strategies have been approached to overcome these issues, but the outcomes are yet to be considered as successful. Recently, superhydrophobic materials or coatings have been brought to attention in various fields. Superhydrophobic surfaces are proposed to be ideal blood-compatible biomaterials attributed to their beneficial characteristics. Reports have substantiated the blood repellence of a superhydrophobic surface, which helps to prevent damage on blood cells upon cell–surface interaction, thereby alleviating subsequent complications. The anti-biofouling effect of superhydrophobic surfaces is also desired in medical devices as it resists the adhesion of organic substances, such as blood cells and microorganisms. In this review, we will focus on the discussion about the potential contribution of superhydrophobic surfaces on enhancing the hemocompatibility of blood-contacting medical devices.

“…Modification of the desired surfaces to render them blood repellent has been conducted using various methods such as atomic layer deposition assisted sacrificial etching [7], sand casting technique [8], oxidation and hydrothermal synthesis [9]. All of these proposed methods require dedicated instrument, cumbersome procedure and could be limited to lab-scale generation of patterned haemophobic surfaces over smaller areas (in range of few millimetres).…”

A low-cost, high-speed micro-scale patterning procedure for generation of durable blood-repellent patterns on polymers using continuous wave (CW) ultraviolet (UV) laser with optical lens arrangement is demonstrated in this work. A laser engraver which can generate patterned structures in the range of 1-300 µm employing a 5 W, 445 nm CW UV laser with collimating lens arrangement was developed for this purpose. Subsequently, cell cast high impact acrylic sheets of 5 cm × 5 cm size were patterned to generate fishbone architecture like microstructures with central structure footprint 71.3 µm, peripheral structure footprint 29.8 µm and peripheral structure spacing of 77.8 µm. The patterned acrylic was evaluated for hydrophobicity and human blood-repellent nature using a contact angle goniometer. Hardness tests for checking durability of the patterned surfaces for various biomedical applications were conducted using a hardness tester. The tested Vickers hardness of the acrylic patterned sample was 17.41 HV which indicates durability of the fabricated patterns. Maximum static contact angle of 142.3°and minimum roll-off angle of 11.7°observed for blood on patterned acrylic confirm the haemophobic nature of the fabricated surfaces.
