“…Air pressure is also a convenient way to control the surface morphology and structure. For example, Li et al [96] reported a facile and scalable pressure-control method for constructing superhydrophobic surfaces with adjustable adhesion. The polytetrafluoroethylene (PTFE) microparticles with uniform size and morphology were first dispersed in fluorinated epoxy resin solution.…”

Superhydrophobic surfaces with expanded wetting behaviors, like tunable adhesion, hybrid surface hydrophobicity and smart hydrophobic switching have attracted increasing attention due to their broad applications. Herein, the construction methods, mechanisms and advanced applications of special superhydrophobicity are reviewed, and hydro/superhydrophobic modifications are categorized and discussed based on their surface chemistry, and topographic design. The formation and maintenance of special superhydrophobicity in the metastable state are also examined and explored. In addition, particular attention is paid to the use of special wettability in various applications, such as membrane distillation, droplet‐based electricity generators and anti‐fogging surfaces. Finally, the challenges for practical applications and future research directions are discussed.

“…2D film material has been widely applied in many fields due to the unique designed structure . The commonly adopted structural design for passive radiative cooling materials can be divided into three categories: multilayered films, metamaterials, and porous structures . The multilayer films usually consist of a thin metal underlayer to achieve high reflectance of the solar radiation in the visible and NIR region .…”

Radiative cooling provides a low-energy consumption remedy for the urban heat island effect. However, most radiative cooling materials use light-colored surfaces to achieve higher reflectivity, which not only causes light pollution problems but also degrades performance after surface contamination. Here, we through the design of the polymer structure used perylene diimide with coloration ability to prepare the crimson polymer perylene poly(aryl ether) (P-FAPE) by simple condensation reaction and prepared the superhydrophobic film with a porous structure by the method of nonsolvent-induced phase transformation. The polymer film has high near-infrared reflectance, with a maximum reflectance of 93% in the near-infrared region and emissivity reaches 95–98% in the atmospheric transmission window. In three days of outdoor testing, the P-FAPE6 film showed an average temperature drop of 5.72–8.52 °C compared to ambient temperature. Importantly, the water contact angle of the P-FAPE6 film is 160°, and the self-cleaning effect prevents the film surface from dirt contamination or wetting in long-term outdoor use. The P-FAPE6 film also demonstrated long-term stability, a V-0 rating for fire resistance in the UL-94 combustion test, which is promising in applications for cooling building facades, outdoor tents, and vehicle sunshades.

“…1,2 Ordinarily when the contact angle is close to 0 (superhydrophilicity) or greater than 150 (superhydrophobicity) between the liquid drop and the contact surface of material, that is called superwetting materials. At present, superwetting materials have been extensively used in self-cleaning, 3 anti-fogging, 4 anti-icing, 5,6 corrosion protection, [7][8][9] oil-water separation, [10][11][12] and other fields. With further research on superwetting materials, it is found that the superwetting interface has a special three-phase contact area and controllable microfluidic characteristics, which can manipulate the transport of liquid, [13][14][15] gas, 16,17 and ions.…”

Wettability is an important property of solid surfaces, superwetting materials can be prepared by controlling the surface morphology and surface energy. In recent years, superwetting materials have been researched and used widely in the fields of self‐cleaning, anti‐fogging, microfluidics, and oil–water separation, but few studies about superwetting materials in chemical reactions have been conducted. In the multiphase reaction, the low solubility and diffusion rate of gas lead to inferior mass transfer, which restricts the reaction kinetics and reduces the reaction rate. Therefore, it may be a breakthrough to make the solid surface obtain underwater superaerophilicity. In this paper, 1H,1H,2H,2H‐perfluorooctyltriethoxysilane (POTS) with low surface energy was constructed on the palladium‐carbon nanotubes (Pd‐CNTs), as‐prepared Pd‐CNTs/POTS composite has excellent hydrophobicity and underwater superaerophilicity. When Pd‐CNTs/POTS composite was utilized in the catalytic hydrogenation, Pd‐CNTs/POTS composite shows higher catalytic activity than Pd‐CNTs; the higher catalytic performance is attributed to the underwater superaerophilicity, which enables gaseous hydrogen to rapidly accumulate on the surface of material, increasing the gas–liquid–solid reaction interface formed. The strategy looks forward to providing a new way for developing novel and efficient heterogeneous catalysts and reaction systems.
