“…Superhydrophobic surface with a high water contact angle (CA) above 150° and low hysteresis has attracted great interest due to their wide applications in microfluidics, windows, anti‐icing coatings, functional textiles and so on 1–3. Numerous works have been focused on the methods of preparing superhydrophobic surfaces, including layer‐by‐layer assembling technique,4, 5 chemical vapor deposition,6 sol–gel method,7–9 phase separation,10–12 and etc 13. However, most of these methods involve complicated process, expensive regents, especial equipment, and special substrates.…”

A superhydrophobic surface was prepared by spin-coating trimethylsiloxane functionalized SiO 2 (TMS-SiO 2 ) solutions onto a precoated polyurethane (PU) layer. The superhydrophobic coatings showed high stability with time, and the prepared coatings remained superhydrophobicity even after 6 months. Furthermore, the as-prepared surface showed high transparency with a transmittance above 70% in visible light region (400-800 nm). The transition of the composite surface from superhydrophobicity to hydrophilicity can be achieved by increasing the drying temperature. More interestingly, the surface showed excellent fluorescent property by the incorporation of fluorescent Europium (Eu) complex into the surface and without deteriorating the superhydrophobic and transparent properties. It was believed that the superhydrophobic surface with multifunction would broaden the applications of superhydrophobic materials.

“…It was reported that trifluoromethyl group (CF 3 )-terminated flat surfaces with the lowest surface energy exhibited the highest WCA of 110∼120° [41][42][43]. The combination of surface chemical composition and rough structure is a key factor determining superhydrophobic surfaces.…”

A fluoropolymer/silica (FP/SiO 2 ) organic-inorganic nanocomposite was synthesized by copolymerization of butyl acrylate (BA), methyl methacrylate (MMA), 2-hydroxyethyl acrylate (HEA), and dodecafluoroheptyl methacrylate (DFMA) based on vinyl nano-silica (V-SiO 2 ) using emulsion polymerization. The V-SiO 2 was prepared via water-based solgel reaction with vinyl trimethoxy silane (VTMS) as the precursor in the presence of the composite surfactant. The preparation of V-SiO 2 , influence of the composite surfactant on VSiO 2 , effect of composite emulsifier on the properties of FP/ SiO 2 , and the formation of the FP/SiO 2 nanocomposite were analyzed. The resulting V-SiO 2 and FP/SiO 2 were characterized by particle size analyzer, transmission electron microscopy (TEM), Fourier-transform infrared spectrometry (FTIR), and X-ray photoelectron spectroscopy (XPS). The obtained FP/ SiO 2 nanocomposites were applied to coat onto the flexible polyester fabrics by dip-pad-cure process. The results showed that the V-SiO 2 nanoparticles had been introduced into the FP/ SiO 2 nanocomposites and superhydrophobic polyester surfaces were achieved by the cooperation of the rough surface structure provided by the silica nanoparticles and the low surface energy caused by fluoropolymer.

“…It can be clearly seen that the difference in contact angles induced by PFPE treatment was much larger for the textured Ni films than the smooth film. This was due to the combination effects of a textured surface and the low surface energy of the material, which could yield a contact angle above 150° and lead to a larger change in contact angle as a result [29,30]. However, chemical modification of the smooth films using PFPE did not produce WCAs above 120°.…”

Nickel (Ni) films with positive and negative textured surfaces of lotus and rice leaf patterns were fabricated through an inexpensive and effective method. The as-prepared Ni films were superhydrophobic and exhibited excellent tribological properties after chemical treatment. Experimental results indicated that the water contact angles (WCAs) on the surfaces of biomimetic textured Ni films (approximately 120°) were far greater than those on smooth films (65°). The biomimetic textured surfaces became superhydrophobic (WCA of approximately 150°) after perfluoropolyether (PFPE) treatment, which could be due to the combined effects of the special texture and the PFPE. The as-prepared biomimetic-textured Ni films modified with PFPE were improved with a low friction coefficient and excellent antiwear properties, which were due to the combination of the effective lubrication of PFPE and the special textures that served as a good lubricant and a debris reservoir. Moreover, the antiwear properties of the as-prepared Ni films with negative biomimetic microtextures modified with PFPE were much better than those of films with positive biomimetic microtextures modified with PFPE.
