“…Until very recently, the commercial use of hydrophobic chemical modifiers, endowing water repellency to any preliminary roughened solid surface, has been hampered due to the low chemical, thermal and mechanical durability of the forming superhydrophobic layer. , Fortunately, the expanding perception of our community that the scientific innovations should ultimately bring societal benefits, has stimulated many scholars to develop ultradurable non-wettable materials capable of withstanding multiple adverse environmental effects and industrial processes. ,− At present, the incorporation of a variety of fluorine and/or silane-based chemicals into the matrix of TiO 2 , SiO 2 , ZnO, polydimethylsiloxane, Fe 3 O 4 /Ag and so forth nanocomposites has led to the launch of unique extremely water-repellent thin films exhibiting exceptional mechanical strength toward abrasive wear, corrosive liquids, UV irradiation, sudden thermal fluctuations and flame exposure, while concurrently supporting oil–water separation, antimicrobial, photocatalytic or anti-icing properties. ,− Nonetheless, the scarce examples for robust superhydrophobic coatings encompassing both icephobic and anti-fouling features remain a major obstacle to the sustainable development of medicine, aerospace and shipbuilding industries. ,, …”

Nowadays, the tremendous progress of nanotechnologies and materials science facilitates the fabrication of universal and multifunctional superhydrophobic surfaces on a large scale. Yet, integrating icephobic and anti-bioadhesive properties in an individual water-repellent functional coating, for addressing the difficulties faced by cryobiologists, aircraft, and seacraft manufacturers, is quite tricky but feasible if using nonpolar soot nanoparticles, whose fragility, however, impedes their industrial applicability. Here, we advance the current state-of-the-art to an extent, permitting the introduction of economically affordable and ultradurable non-wettable soot-based coatings. The deposition of rapeseed oil soot, cyanoacrylate glue and fluorine compounds onto different fabrics confers the latter with superior tolerance to harsh mechanical and thermal interventions [e.g., scratching, blade scraping, liquid nitrogen immersion (T ∼ −196 °C), torsion and water jetting], while in the meantime retaining water repellency and oleophobicity. The as-prepared soot fabrics can stick continuously to the selected host surface and favor the recovery of ∼60% of the initial motility of human spermatozoa subjected to cryopreservation or being detached and utilized as standalone non-wettable membranes. Our invention may be considered as the first fundamental stage of safely (without any health concerns) transferring the soot in reproductive medicine and developing enhanced cryogenic and antibacterial medical devices.

“…Kim and colleagues prepared a colloidal solution by first vapor phase coating of SiO 2 nanoparticles with PDMS at 300 K for 16 h, followed by dispersing the PDMS-coated SiO 2 nanoparticles in the PDMS dispersion of hexane. 28,29 Besides silica nanoparticles, particles such as TiO 2 , [30][31][32][33][34] Ag, 8,35 CuO, 36 ZnO, 37 and Ni(OH) 2 38 have been also used. These inorganic nanoparticles are intrinsically hydrophilic and therefore generally need to be modified with a hydrophobic molecule.…”

Superhydrophobic coatings have large application potential in self‐cleaning textiles. Low durability, high cost of fabrication, and environmental concerns over the usage of chemicals such as fluorocarbons limit the utilization of superhydrophobic coatings. This study reports a convenient and inexpensive approach to fabricate robust and fluorine‐free superhydrophobic fabrics based on the transfer of structured polymer films and hydrophobic nanoparticles. In this approach, polydimethylsiloxane (PDMS) is infused between sheets of fabric and paper, followed by curing and removal of the paper. This process results in a fabric infused with PDMS whose structure is a negative replica of the paper surface. Then, hydrophobic nanoparticles are sprayed onto the structured PDMS side of the fabric. The infusion of PDMS and subsequent deposition of the hydrophobic nanoparticles enables strong bonding, as shown by the excellent solvent stability of the superhydrophobic fabric under ultrasonication. The proposed approach is universal in that it can be applied to almost any textiles, which upon coating, exhibited superhydrophobicity with a water contact angle of 172° and a sliding angle of 3°. Furthermore, the superhydrophobic fabric showed robust durability against water spray impact and mechanical bending where it can keep superhydrophobicity for at least 200 cycles of each test.

“…However, these preparation processes are complicated and involve toxic fluorine-containing materials and gamma ray, which will cause harm to humans. Compared with expensive and toxic fluorinated materials, polydimethylsiloxane (PDMS) possesses the features of chemical inertness, nontoxicity, moderate cost, biocompatibility, and environmental friendliness. − Wang et al prepared a homogenous coating solution by mixing FA (fly ash)–TiO 2 –PDMS particles with PDMS and fabricated multifunctional durable superhydrophobic fabrics by a heat curing method. Therefore, low-surface tension PDMS is a good material to substitute fluorinated materials to prepare superhydrophobic fabrics.…”

In order to solve the problem caused by oil spills and organic solvent contamination, novel magnetically inorganic/organic superhydrophobic fabrics are fabricated via a facile method. Cotton fabrics are immersed in a mixture of functionalized Co 0.2 Mg 0.8 Fe 2 O 4 (FCMFO) nanoparticles, vinyl-terminated polydimethylsiloxane (VPDMS), trimethylolpropane triacrylate, and 2-hydroxy-2-methylpropiophenone before UV irradiation for 100 s to obtain the multifunctional superhydrophobic fabrics with magnetic property. The coated fabrics show excellent superhydrophobicity, and the water contact angle is 157.1°when the mass ratio of FCMFO nanoparticles to VPDMS is 0.3. These superhydrophobic fabrics have high oil/water separation efficiency (98.7% for dichloromethane/water) and high oil flux (71,506 L•m −2 •h −1 for dichloromethane/ water). Even after 20 separation cycles, oil/water separation efficiency and oil flux maintain 96.4% and 64,012 L•m −2 •h −1 , respectively. Furthermore, the magnetic property of these superhydrophobic fabrics could be used in the separation of oil from water. Moreover, the superhydrophobic fabrics possess exceptional self-cleaning performance, mechanical durability, chemical stability, and flame retardancy. These multifunctional superhydrophobic fabrics are potential for wide applications.
