“…Besides, many tiny SiO 2 nano‐protrusions on the surface of WPCBP endow the coatings with high roughness, and SiO 2 nano‐protrusions can be responsible for trapping air to create a hydrophobic resistance against water penetration. [ 27 ] The WCA of the PDMS/WPCBP@SiO 2 coating reaches 158° (inset in Figure 5A). In Figure 5C,D, when the mass ratio of PDMS and WPCBP@SiO 2 is 0.6, the surface of WPCBP@SiO 2 was enveloped by a thin layer of PDMS.…”

Reutilization of waste printed circuit board nonmetal powders (WPCBP) has been one of the major bottlenecks in the comprehensive utilization of electronic wastes. Herein, a new reutilization strategy of WPCBP was innovatively proposed to develop a superhydrophobic coating. Typically, WPCBP@SiO2 hybrid filler was successfully prepared by the in‐situ growth of silica on WPCBP surface, and the structures and compositions of WPCBP@SiO2 were systematically investigated by SEM, FTIR, and TGA. Then the obtained WPCBP@SiO2 was combined with polydimethylsiloxane (PDMS) to prepare a superhydrophobic coating. The as‐prepared PDMS/WPCBP@SiO2 coatings exhibited excellent superhydrophobicity and self‐cleaning ability, whose static water contact angle (WCA) is more than 150° while the sliding angle (SA) is <10°. In summary, this study provides a green and efficient reutilization strategy of WPCBP in superhydrophobic coatings, which may open up a new opportunity for the high‐valued utilization of WPCBP.

“…To reduce the surface energy of the cotton fabric, the main strategy involves coating the cotton fabric with some uoropolymer (Xu et al 2020b;Yang et al 2018a;Yang et al 2018b), polyester (Wang et al 2014;Xi et al 2016), and silane polymer (Eduok et al 2021;Ge at al. 2020;Kim et al 2020).…”

Improving the surface roughness and reducing the surface energy are the main strategies for constructing cotton fabrics with superhydrophobic surface. However, the complex nishing process and poor durability still impede the production and application of superhydrophobic cotton fabrics. Therefore, it is critical to produce superhydrophobic fabrics with excellent durability via a noncomplicated method.In this work, monomers of methyl methacrylate (MMA) and tri uoroethyl methacrylate (TFMA) were polymerized via free radical polymerization to produce a uoropolymer. Then, the fabric was coated with the uoropolymer to construct a superhydrophobic surface via the pad-dry-cure technology. The TFMA unit in the uoropolymer had lower surface energy than the MMA unit. Under the high-temperature curing condition, the MMA unit in the uoropolymer was grafted onto the cotton fabric via transesteri cation, and the TFMA was exposed on the fabric surface. The nished fabric showed durable superhydrophobic properties, outstanding oil-water separation properties, and excellent self-cleaning properties. Given the results, the nished fabric has great potential application in clothing and industrial elds.
