“…However, the thickness and properties of such films are important and the objective is to obtain the situation where the incident light and the reflected light are exactly out of phase. Some type of SH surfaces were utilized as antireflective coatings [56][57][58][59][60]. The simplest form of an anti-reflective coating can be produced from a single transparent thin layer having a refractive index which is equal to the square root of the refractive index of the substrate.…”

“…Transparent surfaces with light transmittance value above 85% and having both selfcleaning property and anti-reflection ability indicate a great industrial value. Thus, the size of surface roughness should be carefully controlled to fabricate such SH surfaces [20,[56][57][58][59][60].…”

“…Surface plasma treatment, lithographic and template-based techniques were employed as top-down methods. Solution casting using polymer/ inorganic mixtures, phase separation and electrospinning were the hybrid methods to combine the bottomup and top-down approaches [52,60]. However, a very suitable method is still lacking to coat the large area of glass or transparent polymer surfaces to form a SH surface.…”

S üperhidrofob yüzeylerin endüstrideki kullanımı, son 20 senedir araştırma laboratuvarlarında yapılan yoğun çalışmalara rağmen tatmin edici bir seviyede değildir. Bu derleme makalesinde, bu negatif durumun sebepleri bazı alt başlıklar altında tartışılmıştır. En önemli sorunlar, SH yüzeylerin mekanik dayanımlarının zayıf olması ve açık hava koşullarında meydana gelen kaçınılmaz kontaminasyonun bunların kullanım süresini kısaltmasıdır. SH yüzeylerin eldesi için zayıf ve ince yapıların yüzeyde olmasına ihtiyaç vardır ve bu durum da bu yüzeylerin mekanik dayanımını azaltmaktadır. Tartışılan diğer sorunlar, gereksiz yere laboratuvarlarda yapılan ve ancak küçük alan kaplayabilen pahalı sentezler, şeffaf ve kendini onaran SH yüzey elde edilmesindeki sorunlar ve SH yüzeylerin buzu itme çalışmalarındaki başarısızlığıdır. Anahtar Kelimeler Süperhidrofob, kaplama, su itici, endüstriyel uygulama.

“…To circumvent the limitations associated with lubricant evaporation, high-viscosity medical-grade silicone oils have been used as alternatives to fluorocarbon-based lubricants in various lubricant-infused platforms. Like fluorine-based LIS, these surfaces resist nonspecific adhesion and exhibit multiliquid repellency properties toward biofluids and aqueous and organic solvents. ,,,− …”

Like all biofluid-contacting medical devices, intranasal splints are highly prone to bacterial adhesion and clot formation. Despite their widespread use and the numerous complications associated with infected splints, limited success has been achieved in advancing their safety and surface biocompatibility, and, to date, no surface-coating strategy has been proposed to simultaneously enhance the antithrombogenicity and bacterial repellency of intranasal splints. Herein, we report an efficient, highly stable lubricant-infused coating for intranasal splints to render their surfaces antithrombogenic and repellent toward bacterial cells. Lubricant-infused intranasal splints were prepared by creating superhydrophobic polysiloxane nanofilament (PSnF) coatings using surface-initiated polymerization of n-propyltrichlorosilane (n-PTCS) and further infiltrating them with a silicone oil lubricant. Compared with commercially available intranasal splints, lubricant-infused, PSnF-coated splints significantly attenuated plasma and blood clot formation and prevented bacterial adhesion and biofilm formation for up to 7 days, the typical duration for which intranasal splints are kept. We further demonstrated that the performance of our engineered biointerface is independent of the underlying substrate and could be used to enhance the hemocompatibility and repellency properties of other medical implants such as medical-grade catheters.

“…When it is used together with polydimethylsiloxane as a water repellent finishing agent to finish the fabric, not only is the water repellency marvelous, but the film forming property and hand feel are also improved [ 17 ]. In addition, hydroxyl-modified polysiloxanes, amino polysiloxanes and amino-modified fluorinated polysiloxanes are also commonly used as water repellents to endow fabrics with more durable water repellency [ 18 ].…”

Water repellent is an important functional finish for cotton fabric. However, cotton fabrics often have poor washing resistance and other performances after actual finishing. In this study, based on the structural characteristics of cotton fiber and durability of water repellent, a cross-linked amino long-chain alkyl polysiloxane (CAHPS) was first prepared, and then reacted with modified silica. Finally, a chemically bonded organic–inorganic nanohybrid cross-linked polysiloxane (rSiO2-CAHPS) was fabricated. Furthermore, the rSiO2-CAHPS was emulsified to obtain a durable fluorine-free water repellent. The water repellent finishing for cotton fabric was carried out by the pad–dry–cure process. After finishing, the cotton fabric had good resistance to conventional liquids and excellent washing resistance, and still maintained good water repellency after 30 rounds of soaping. Moreover, properties including air permeability, mechanical property and whiteness are hardly affected after finishing. SEM and XPS characterization show that a layer of dense silicon film is formed on the surface of cotton fabric by rSiO2-CAHPS water repellent. The existence of nanosilica can improve the surface roughness of cotton fibers. The synergistic effect of fiber matrix, nanoparticles and CAHPS endows the fabric with a micro/nano-multi-scale micro-rough structure, which improves the water repellency of cotton fabric after water repellent finishing.
