“…During last years, research on superhydrophobic surfaces has been widely developed due to their numerous industrial applications [2]. Different researchers show that it is possible to artificially generate hydrophobic surfaces by reproducing the surface patterns observed in nature, using different techniques (lithography, templating, plasma treatment, sol-gel methods) [1,3]. However, some of these methods alter the aesthetic appearance of the substrate.…”

In the context of increasing industrial importance of superhydrophobic surfaces, three different pretreatments on an austenitic stainless steel surface have been tested to be coated with a silane-based solution containing SiO 2 nanoparticles, in order to obtain superhydrophobic surfaces. The pretreatments are (i) an acetone degreaser, (ii) this one followed by a hot air treatment and acid pickling, and (iii) the previous one followed by an alkaline etching. Pretreated surfaces have been characterized by X-ray photoelectron spectroscopy, tapping-mode atomic force microscopy and contact angle measurements. After the three pretreatments, a solution of methyltrimethoxysilane and tetraethoxysilane in white spirit solvent and 1% of SiO 2 (% by wt.) has been used to prepare a superhydrophobic coating on them. The hydrophobicity of the developed coatings has been studied using water contact angle measurements (static angles and advancing and receding angles). Besides, scanning electron microscope has been used to study the coatings. The results show that different tailored surfaces can be obtained in stainless steels using these pretreatments, obtaining surfaces that exhibit different physicochemical characteristics that may condition the formation of superhydrophobic coatings on them.

“…Das et al [8] examined the fabrication of robust superhydrophobic surface on glass using ZnO at high temperature curing (400°C). Simovich et al [35] fabricated a robust superhydrophobic surface by the combination of epoxy resin, hexamethylenediamine, and silica nanoparticles. Nevertheless, the hydrophobic solution was maintained at a temperature in the range of 70-80°C, the substrate was heated to 150°C prior to spraying process, and then it was cured at 130°C for 24 h. All these techniques with high temperature curing and multiple steps are not favorable for industrial applications.…”

In this present work, a superhydrophobic glass surface comprising zinc oxide nanotriangles (ZnO-nt) and nontoxic silylating agent was developed via a cost-effective spray-coating technology. ZnO-nt was synthesized by a hydrothermal method. Poly(dimethylsiloxane) (PDMS) and dimethyldiethoxysilane (DMDEOS) were used as nontoxic (nonfluoro) silylating agents. The morphology and crystallinity of ZnO-nt were studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. ZnO-nt with polymeric silane (PDMS) exhibited maximum wettability as compared to nonpolymeric silane (DMDEOS). The water contact angle (WCA), sliding angle (SA), and surface roughness of ZnO-nt/PDMS-coated glass substrate under UV treatment were 165 ± 1°, 3 ± 1°, and 791 nm, respectively. The WCA of ZnO-nt/PDMS was higher (165°) than that of commercial ZnO/PDMS (ZnO-C/PDMS). ZnO-nt/PDMS was strongly attached to the glass substrate with good stability and adhesion. The reasons for improved hydrophobicity, adhesion, and mechanism of hierarchical microstructure formation on the glass substrate were explained in detail. PDMS was attached to the glass substrate via hydrogen bonds from solvated zinc acetate.
