Waterproof surfaces have attracted much attention due to their special properties such as self-cleaning, low adhesion of water and inorganic liquids, and water repellency. An important advantage of hydrophobic surfaces in industry is the enhanced corrosion resistance of metal utensils. The wettability of a surface is determined by the values of water contact angle (WCA) and sliding angle (SA). Surfaces are called hydrophobic and superhydrophobic if greater than WCA > 90° and if WCA > 150° and SA < 10°, respectively. In order to prepare hydrophobic surfaces and even superhydrophobic surfaces, two parameters are crucial to obtain, including nano/micro high surface roughness and low surface energy.
Seyed Masoud Emarati et al. used trimethoxypropylsilane (TMPSi) modified titanium dioxide nanoparticles to prepare superhydrophobic coatings on AISI 316L stainless steel substrates by electrophoretic deposition (EPD). In this work, the main role of TMPSi is to reduce the surface energy through chemical modification. The WCA and SA of the best sample (1.5 vol.% TMPSi) were equal to 160.1° and 3.7°, respectively, which indicated the successful preparation of the superhydrophobic surface.
