“…The number of bouncing cycles of water droplet on a superhydrophobic surface depends upon the surface microstructure, surface tension and static contact angle. [31][32][33][34][35][36][37] The replica from 1 min-plating SiNW has the lowest water CA (138 ). For other PDMS replicas that have comparable water CA (around 150 ) and same PFOTS-uorinated process, the key factor that inuences water bouncing behavior is the surface microstructures, that is, the spacings between nanopatterned micropillars.…”

“…In this paper, PMMA particles (10-50 µm) and nanosilica particles (15-50 nm) were used to construct the micro-nano rough structure using a spraying method with PVDF as the matrix. The nano-SiO 2 was prepared using a hydrothermal method [16]. Then, 0.5 g of nano-SiO 2 , 0.5 g of polydimethylsiloxane, 0.05 g of dibutyltin dilaurate, and 50 mL of heptane were placed in a three-necked flask.…”

Pollution flashover accidents pose a great threat to the safe and stable operation of a power system, and superhydrophobic materials have broad application prospects in the field of pollution flashover prevention of the external insulation of transmission and transformation equipment. In this paper, PVDF@PMMA/SiO2 superhydrophobic coatings were prepared using a spraying method. Superhydrophobicity is defined as an angle larger than 150° and a small roll-off angle smaller than 10°. The static contact angle of the coatings reached 155°, which meant they had excellent superhydrophobic properties. The distribution characteristics of water droplets on superhydrophobic surface were analyzed through a live condensation test, and simulation analysis was carried out. It was found that the distance between water droplets on the superhydrophobic surface was larger, which increased the distance of the arc development; the static contact angle was larger; and the electric field strength at the three-phase junction was lower. Both of them worked together to enhance the pollution flashover voltage of the coating.

“…Numerous efforts have been made to inhibit metal corrosion, including organic coatings [1][2][3], inhibitors [4,5], cathodic protection [6] and surface modification [7]. Inspired by lotus leaves, a superhydrophobic surface with a water contact angle greater than 150°and rolling angle smaller than 10°, has attracted great attention over the past decades, because it presents significant potential in the fields of selfcleaning [8,9], corrosion resistance [10][11][12], oil-water separation [13] and energy conservation [14].…”

A superhydrophobic surface featuring high roughness and low surface energy is designed for effective corrosion protection on aluminum via a facile and cost-effective electrochemical route. The effects of the electrolyte composition and electrodeposition time on the surface wettability were investigated. Moreover, the corrosion resistance performance of the as-prepared superhydrophobic aluminum surface was studied using electrochemical impedance spectroscopy and electrochemical noise techniques. The results show that the superhydrophobic aluminum surface obtained at 2 V for 20 min has a high static water contact angle of 155.8°. Both the average corrosion rate and pitting intensity are remarkably inhibited by the as-prepared superhydrophobic surface on aluminum. Moreover, the static water contact angle for the obtained superhydrophobic surface remains above 150°after exposure to 3.5 wt% NaCl solution for 30 days. This facile and economical superhydrophobic surface, with its excellent anti-corrosion property and stability, shows significant potential for use in industrial applications.

Efficiently texturing hierarchical superhydrophobic fluoride-free translucent films by AACVD with excellent durability and self-cleaning ability

Abstract: Robust fluoride-free translucent superhydrophobic coatings were constructed on glass surfaces via one-step aerosol-assisted chemical vapour deposition technique. There are 9 bounce cycles observed on such hierarchically structured surfaces, which exhibited excellent self-cleaning ability.
