Owing to its hydrophobic nature, polymers are more commonly employed to impart superhydrophobicity over different surfaces. This review gives a brief account on the theories behind superhydrophobicity and techniques employed to develop superhydrophobic coatings over metal, fabrics, papers, sponges, foam, glass, wood, mesh, concrete and ceramic surfaces. Fine‐tuning of superhydrophobic polymeric surfaces is much required to enhance corrosion control, oil‐water separation, self‐cleaning, drag reduction, anti‐microbial, anti‐bio‐fouling, anti‐icing and desalination properties. Methodology and current developments in the designing such superhydrophobic polymeric surfaces are highlighted. To conclude, the challenges to be addressed by the scientific world to solve the problems associated with mass production, stability and durability of the coatings, development of hierarchical micro‐nanostructures are detailed.

“…Achieving antibacterial superhydrophobic fabrics is challenging due to the uneven topography and geometry of fibers in the structure of a fabric, which can inevitably provide suitable sites for the adhesion of microorganisms and forming biofilms. Song et al, Gu et al, Ye et al, and Bu et al have reported various antibacterial superhydrophobic coatings on textiles. Among different types of antibacterial agents, silver has widely been utilized in developing antibacterial coatings due to its strong ability to inhibit the growth of a wide variety of pathogenic microorganisms. , Various types of antibacterial textiles such as wool, , silk, , cotton, , nylon, and polyester have been developed after treatment with silver nanoparticles.…”

Cotton fabrics with superhydrophobic, antibacterial, UV protection, and photothermal properties were developed using Ag/PDMS coatings, and the role of coating formulations on the obtained functionalities was studied. Specific attention was paid to understanding the relationships between the fabrics’ superhydrophobicity and antibacterial activity against Escherichia coli (E. coli) bacteria. UV protection performance of Ag/PDMS coatings was thoroughly evaluated based on the variation of UV transmission rate through coated fabrics and photoinduced chemiluminescence spectra. Moreover, the effect of silver nanoparticles (Ag NPs) and PDMS on developing a photothermal effect on fabrics was discussed. It was found that the content of Ag NPs and PDMS played critical roles in determining the water contact angle (WCA) on modified fabrics. The largest WCA was 171.31°, which was durable even after numerous accelerated wash cycles and abrasions. Antibacterial activity of fabrics showed the positive effect of pure PDMS in bacterial growth inhibition. Moreover, it was found that the antibacterial performance was greatly affected by the content of Ag NPs loaded on fabrics rather than their superhydrophobic status. Moreover, increasing the content of Ag NPs boosted the UV protection level of fabrics, improved fabrics photostability, and reduced the UV transmission rate through fabrics. Testing the photothermal effect confirmed that the content of Ag NPs and PDMS both played prominent roles, where Ag acted as a photothermal agent and PDMS determined the NIR reflection rate from the coated surface. The modified fabrics were characterized using TGA, SEM, FTIR, and XRD techniques, and it was confirmed that using a higher amount of PDMS increased the amount of Ag NPs deposition on fabrics.

“…In recent years, antiwetting cellulose fabric possessing durable resistance to water was largely investigated owing to their wide applications in the outdoor sporting, medical, and protective textile markets. [1][2][3] Fluorine-containing water repellents have become most favorable hydrophobic agents over the past years. Their excellent water-repellent properties, chemical stability, and washing resistance explained why they have been used in different industrial fields, such as coatings, decorative materials, paints, and textiles.…”

In this work, cationic waterborne polyurethane/acrylate (WPUA) was synthesized for water repellent in cotton fabrics to replace fluorine‐containing finishing agents with the concerns of ecosystems and human health. First, the tertiary amines monomers, N‐methyl diethanolamine, 3‐dimethylamine‐1, 2‐propylene glycol, N,N′‐bis (2‐hydroxyethyl)piperazine, were used as chain extenders to prepare waterborne polyurethane, respectively. Long‐chain octadecyl acrylate monomers were then grafted to the waterborne polyurethane by a self‐emulsifying method. The stable WPUA suspensions of positively charged latexes were obtained and could be finished on cotton fabrics via a simple pad‐curing process. The coated cotton fabrics were capable of repelling common liquids without any penetration, and the contact angles of the treated cotton fabrics could reach 150°. The WPUA latex films also exhibited good tensile mechanical properties and thermal dimensional stability. The cotton fabric coated with the WPUA showed good laundering durability, and its static water contact angle was still maintained at 142° even after 50 times washing. This work not only highlights the structural design and preparation but also provides a feasible strategy for fluorine‐free water repellency in cotton fabrics, which has great potential application prospects for a variety of fields.
