Herein, a superhydrophobic Ni coating is prepared on 316L stainless steel by electrodeposition and low energy modification with tetradecanoic acid. After 20 min of electrodeposition with a current density of 8 A dm−2, a Ni coating with micro–nano dual‐scale structures is obtained. The coating becomes superhydrophobic with a water contact angle (WCA) of 160.4° and a sliding angle (SA) of 8.3° after being immersed in the tetradecanoic acid solution (5 g L−1, 12 h). A two‐level structure model is established for explaining the effect of morphology on the wettability of the coating. The WCA value of the superhydrophobic Ni coating retains above 150° after being exposed in outdoor environment for 6 months and in flowing environment for 7 days. In addition, the coating still shows superhydrophobicity after 9 times of mechanical abrasion test, 12 h of acid soaking (pH = 1), and 16 h of heat treatment in 200 °C. Moreover, the coating improves the corrosion resistance of the steel substrate. This superhydrophobic Ni coating provides a simple method to prevent stainless steel from corrosion. And the theoretical calculation of the two‐level model can provide an innovative strategy for designing the structure of the superhydrophobic coating.

“…However, the organic coatings usually deteriorate upon UV exposure, decreasing the self-cleaning properties of superhydrophobic films. Recently, some researchers have developed several UV-durable superhydrophobic materials to address this limitation [22,23,24,25]. Wong and coworkers synthesized durable coatings with superhydrophobicity through template-free micro-nano texturing of interpenetrated polymer networks [22].…”

Superhydrophobic materials have immense applications in the fields of industry and research. However, their durability is still a cause for concern. A facile method for preparing durable superhydrophobic films from carbon nanotubes (CNTs) and the main-chain type polybenzoxazine precursors is reported herein. We used probe ultrasonicator to prepare CNT/polybenzoxazine coatings. Compared with the general sonicating dispersion process, the dispersion time was greatly reduced from a few hours to 5 minutes and the prepared suspension exhibited film-forming characteristics well. The CNT/polybenzoxazine films, which do not contain any fluorinated compounds, exhibit remarkable durability against thermal treatment, organic solvents, corrosive liquids, and sandpaper abrasion, while retaining their superhydrophobicity. Furthermore, these CNT/polybenzoxazine films also showed durable superhydrophobicity after ultraviolet (UV) irradiation for 100 h. This CNT/polybenzoxazine film can be readily used for practical applications to make durable superhydrophobic coatings.

“…In recent decades, surface functionalization has been proven particularly effective in realizing unique textiles with desired properties such as self-cleaning, antibacterial, antifungal, fl ame retardancy, ultraviolet blocking and superhydrophobic [1][2][3][4][5][6]. In view of the close relationship with our daily life, the self-cleaning and antibacterial textiles are especially attractive.…”

This study discusses the effect of corona pretreatment and subsequent loading of titanium dioxide nanoparticles on self-cleaning and antibacterial properties of cellulosic fabric. The corona-pretreated cellulosic fabrics were characterized by field emission scanning electron microscopy, and X-ray mapping techniques revealed that layers of the titania deposited on cellulose fibers were more uniform than the sample without pre-corona treatment. The self-cleaning property of treated fabrics was evaluated through discoloring dye stain under sunlight irradiation. The antibacterial activities of the samples against two common pathogenic bacteria including Escherichia coli and Staphylococcus aureus were also assessed. The results indicated that self-cleaning and antibacterial properties of the corona-pretreated fabrics were superior compared to the sample treated with TiO2 alone. Moreover, using corona pretreatment leads to samples with good washing fastness.
