“…Surprisingly, the fabric barely loses 5 % of its contact angle after 10 cycles of handwashing with detergents and soaking in hot water, thereby, gathering interest in the field of anti-fouling, selfcleaning and corrosion-resistance applications. [45] A UV-cured fluoride-free pH-responsive polyurethane (pH-PU) based smart coating on pristine textiles was fabricated by Chaoxia and his group. The coating was formed by dip coating polyhedral oligomeric silsesquioxane (POSS) and lauryl diethanolamine (LDEA) containing polyurethane resin onto pristine textiles, which are then irradiated with UV light (Figure 5).…”

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.

“…Superhydrophobic polymer composite materials have been the subject of extensive research due to their unique properties and potential applications in various fields such as self-cleaning surfaces, anti-icing, and drag reduction [6,7]. These materials possess high water repellency, with water droplets easily rolling off their surfaces, leaving no trace [8].…”

This study aims to enhance the practical performance of PVDF/ZnO and PVDF/TiO2 composite coatings known for their distinctive properties. The coatings, applied through spray coating with PVDF and ZnO or TiO2 nanoparticles on glass, steel, and aluminum substrates, underwent a comprehensive evaluation. Surface wetting properties and morphology were respectively evaluated using a technique involving liquid droplets and an imaging method using high-energy electrons. Potentiodynamic polarization was used to compare corrosion resistance between coated and bare substrates. Nanoindentation was used to assess coating hardness, and bonding strength was subsequently quantified. The results revealed that PVDF/ZnO composite coatings had higher water contact angles (161 ± 5° to 138 ± 2°) and lower contact angle hysteresis (7 ± 2° to 2 ± 1°) compared to PVDF/TiO2 and PVDF coatings. Moreover, corrosion tests demonstrated superior protection for steel and aluminum surfaces coated with superhydrophobic PVDF/ZnO. Nanoindentation indicated enhanced mechanical properties with TiO2 nanoparticles, with adhesion results favoring TiO2 over ZnO nanoparticles.

“…The polymer contributes to the formation of a matrix structure that can be tuned by the interactions between polymers and solvent and the polymer/solvent ratio [9]. Superhydrophobic surfaces made from PP have been studied by several authors due to the intrinsically hydrophobic nature of PP and their great price-performance ratio [10]. First, Erbil et al [11] reported on superhydrophobic PP surfaces using the phase separation method with the appropriate selection of solvents, non-solvents, and cooling temperatures.…”

In this study, we prepared polypropylene sheets with a superhydrophobic surface from extruded sheets with a phase separation method. We investigated the influence of extrusion parameters on the morphological properties of the polypropylene sheet and found that two significantly different structures can be formed in the cross-section of the sheet when the cooling temperature was varied. The effect of the morphology of the extruded material was studied on phase separation and through that on the surface structure that formed. The created morphology of the extruded sheet plays a significant role in the procedure of the phase separation method and less in surface wettability. We also included a polypropylene blend and nucleated polypropylene in this study to investigate their role in surface morphological changes and indirectly on wetting behavior. Surfaces have become superhydrophobic with an increased water contact angle from 102° to 150° and contact angle hysteresis below 10°. For nucleated polypropylene samples, we achieved remarkably good results (a water contact angle of 158°). The morphological and wettability behavior of the surfaces were investigated with a polarized optical microscope and water contact angle measurements, and scanning electron microscopy, respectively.
