“…The changes in the surface chemical composition were measured via energy-dispersive X-ray spectroscopy (EDS) [ 44 ] and X-ray photoelectron spectroscopy (XPS) to obtain the surface properties related to superhydrophobicity. Independent of the fiber type, the untreated fabrics consisted of carbon and oxygen [ 23 ] ( Figure 3 a,c and Supplementary Materials Figure S1 and Table S1 ). However, after P1T1 PDSM coating, both fabrics contained silicone (Si) on the surface [ 45 ], but the filament fabric had higher Si content (1.19% in Figure 3 and 21.3% in Supplementary Materials Table S1 ) than the staple fabric (0.47% in Figure 3 and 11.8% in Supplementary Materials Table S1 ).…”

“…Some studies investigated the effect of the number of monofilament [ 19 ] and yarn types (filament and Drawn Textured Yarn, DTY) [ 20 ] on superhydrophobicity. Micro/nano hierarchical roughness is important to create superhydrophobicity and self-cleaning property [ 21 , 22 ], but nano roughness created by these methods can be easily damaged during use, leading to a decrease in superhydrophobicity [ 23 , 24 ]. Thus, some superhydrophobic surfaces are made without the nano structures [ 25 , 26 ], because micro/micro hierarchical structures without nano roughness have high mechanical robustness and potential to be used in mass production [ 27 , 28 ].…”

In this study, we proved that micro/micro hierarchical structures are enough to achieve a superhydrophobic surface using polydimethylsiloxane (PDMS) dip-coating. Furthermore, the effect of fiber type and yarn diameter on superhydrophobicity and water spray resistance was investigated. Polyester fabrics with two types of fibers (staple fabric and filament) and three types of yarn diameters (177D, 314D, and 475D) were used. The changes in the surface properties and chemical composition were investigated. Static contact angles and shedding angles were measured for superhydrophobicity, and the self-cleaning test was conducted. Water spray repellency was also tested, as well as the water vapor transmission rate and air permeability. The PDMS-coated staple fabric showed better superhydrophobicity and oleophobicity than the PDMS-coated filament fabric, while the filament fabric showed good self-cleaning property and higher water spray repellency level. When the yarn diameter increased, the fabrics needed higher PDMS concentrations and longer coating durations for uniform coating. The water vapor transmission rate and air permeability did not change significantly after coating. Therefore, the superhydrophobic micro/micro hierarchical fabrics produced using the simple method of this study are more practical and have great potential for mass production than other superhydrophobic textiles prepared using the chemical methods.

“…Chemical vapor deposition (CVD) is a method of producing thin films by chemical reaction on a substrate surface using one or several vapor compounds or elements. Guo et al fabricated a superhydrophobic surface by aerosol-assisted layer-by-layer chemical vapor deposition (AA-LbL-CVD) of epoxy resins and polydimethylsiloxane (PDMS) polymer films [25]. The obtained surface demonstrated well anti-UV light irradiation and even great mechanical stability.…”

Superhydrophobic surfaces have drawn attention from scientists and engineers because of their extreme water repellency. More interestingly, these surfaces have also demonstrated an infinite influence on civil engineering materials. In this feature article, the history of wettability theory is described firstly. The approaches to construct hierarchical micro/nanostructures such as chemical vapor deposition (CVD), electrochemical, etching, and flame synthesis methods are introduced. Then, the advantages and limitations of each method are discussed. Furthermore, the recent progress of superhydrophobicity applied on civil engineering materials and its applications are summarized. Finally, the obstacles and prospects of superhydrophobic civil engineering materials are stated and expected. This review should be of interest to scientists and civil engineers who are interested in superhydrophobic surfaces and novel civil engineering materials.

“…This work demonstrates that on the superhydrophobic SMP surface, both the damaged surface microstructure and chemistry can be self‐healed under a simple heat treatment (Figure 5a). Recently, similar self‐healing ability in surface microstructure and superhydrophobicity was further demonstrated on some other SMPs, such as the epoxy resins/PDMS polymer film, [ 45 ] microspike‐structured vulcanized rubber, [ 46 ] and pH‐responsive capsule‐decorated epoxy‐resin micropillar arrays. [ 47 ] In addition to the simple restoration of surface superhydrophobicity, through combining the corrosion inhibitor benzotriazole (BTA) and the epoxy‐based SMP, Zhang et al.…”

Superwetting Shape Memory Microstructure: Smart Wetting Control and Practical Application

Smart control of wettability on superwetting surfaces has aroused much attention in the past few years. Compared with traditional strategies such as adjusting the surface chemistry, regulating the surface microstructure is more difficult, though it can bring lots of new functions. Recently, it was found that, based on the shape memory effect of a shape memory polymer, the surface microstructure can be controlled more easily and precisely. Here, recent developments in the smart control of wettability on superwetting shape memory microstructures and corresponding applications are summarized. The primary concern is the superhydrophobic surfaces that have demonstrated numerous attractive functions, including controllable droplet storage, transportation, bouncing, capture/release, and reprogrammable gradient wetting, under variation of the surface microstructure. Finally, some achievements in wetting control on other superwetting surfaces (such as superomniphobic surfaces and superslippery surfaces) and perspectives on future research directions are also discussed.
