“…Cao et al also tested the permeability of heat-reflective pavements, finding that they are basically impermeable because the coating almost seals their surface, preventing water from entering the concrete interior and, hence, avoiding asphalt and pavement damage [12]. The microstructures of the heat-reflective coatings and their components have been investigated via scanning electron microscopy [16,18,23,26,[28][29][30][31][32]. Moreover, Hu et al performed accelerated wear tests to study the wear performance of these coatings; the results showed quality loss after wearing, but an improved anti-skid granular stirring method could enhance the wear performance [17,24,33].…”

Heat-reflective coatings, used to reduce the asphalt pavement temperature and urban heat island effect, have a good cooling effect; coating development, however, generally focuses on cooling. This study aims to design a heat-reflective coating with both durability and cooling effect by considering the functions of each component, improving the coating bond strength and abrasion resistance, and conducting laboratory tests and test section verification. The coating developed exhibits bond strength and abrasion resistance 20% and 49%, respectively, higher than those of ordinary coatings. The experiments reveal a cooling effect of red coating up to 10.2 °C, a bond strength of up to 1.20 MPa at 25 °C, and an abrasion rate of up to 25% after 60 min; the cooling effect is basically the same as that for traditional heat-reflective coatings, but the bond strength and abrasion resistance significantly improved. In the analysis of the test section, the cooling effect reaches 7.0 °C, the performance of anti-skid decreases little, and the coating is still usable normally after 4 months.

“…mixed black infrared‐reflective pigments, fluorinated acrylic resin emulsion, and a small amount of SiO 2 nanoparticles with silicon resin emulsion to coat an Al substrate. [ 97 ] Excellent soil‐repellent and infrared‐reflective properties were obtained and a 30 °C lower temperature was observed compared to the control groups. In addition, the superhydrophobic coating prepared by mixing diatomaceous earth@SiO 2 with fluorosilicone resin showed excellent anti‐bioadhesion to Aspergillus and Simplicillium , mechanical robustness, and long‐term waterproofing and thus can be potentially used for mildew proof.…”

the emergence of bionics. Although it has only been around for ≈60 years, bionics has undeniably spread to and revolutionized almost every aspect of human life. Special wettability, one of the most common phenomena in nature, was described as early as in 1805 with Young's equation. [1] However, it was not until 1976 that the term "superhydrophobicity" was first introduced to describe the particle coating of hydrophobic fumed silicon dioxide, on which water droplets remained spherical and the adhesion force was negligible. Later, in 1997, Barthlott [2] and Neinhuis [3] reported the "lotus effect" and revealed the origin of the self-cleaning property of lotus leaves: the presence of papillae on the microstructure and epicuticular wax. Subsequently, Jiang et al. further deciphered that the nanostructures on the top of the micropapillae impart superhydrophobicity to the surface of lotus leaves. [4] At the same time, it was discovered that many other naturally occurring phenomena are due to the superhydrophobicity of materials, [5] such as the high and directional adhesion of gecko foot, the structural color of butterfly wings, the anisotropic wetting of rice leaves, the low fluid friction of water strider legs, the antifogging and anti-reflection of mosquito compound eyes, the high adhesion of red rose petals, the low adhesion of cicada wings, the high reflection of poplar leaves, and the water capture of Stenocara beetles, etc. To date, great efforts have been made to establish theoretical models to understand superhydrophobic phenomena, develop advanced strategies and techniques to fabricate superhydrophobic surfaces, and exploit the versatile properties and functions of superhydrophobic materials. [6] However, it is still a great challenge to translate superhydrophobic phenomena in nature into practical applications by mimicry. Fortunately, after thorough investigations, researchers have found that sufficient roughness and suitable surface energy are the two indispensable determinants to impart superhydrophobicity to synthetic materials. [7] Applications of superhydrophobic materials in transportation, architecture/building protection, oil/water separation, and seawater desalination to biomedical device fabrication, biosensing, energy conversion and utilization, and textile manufacturing, have been studied extensively over the past decade (Figure 1). [8] An analytical report published by Mordor Inspired by the lotus leaf in nature, superhydrophobic materials have attracted considerable attention in both science and industry over the past three decades. Apart from the most characteristic yet widely used properties such as waterproofing, anti-fouling, and self-cleaning, superhydrophobic materials have also developed exciting new functions such as drag reduction, corrosion resistance, anti-icing, anti-bacteria, and anti-reflection. In this review article, the theoretical models describing superhydrophobic surfaces are first briefly introduced. Then, the most common substrates and strategies for fabricating super...

“…At present, the most common method is to change the environmental conditions to achieve the condensation of water droplets on the material surface. For example, by increasing humidity through artificial sprays [21], artificial rainfall [22,23], etc. and meeting the requirements of the environmental dew point, condensation on the material surface can be formed.…”

Self-cleaning of superhydrophobic nanostructured surfaces at low humidity enhanced by vertical electric field

Self-cleaning is the key factor that makes superhydrophobic nanostructured materials have wide applications. The self-cleaning effect, however, strongly depends on formations and movement of water droplets on superhydrophobic nanostructured surfaces, which is greatly restricted at low humidity (< 7.6 g•kg −1 ). Therefore, we propose a self-cleaning method at low humidity in which the pollution is electro-aggregated and driven in the electric field to achieve the aggregation and cleaning large areas. The cleaning efficiency of this method is much higher than that of water droplet roll-off, and will not produce " pollution bands" . A simplified numerical model describing pollution movements is presented. Simulation results are consistent with experimental results. The proposed method realizes the self-cleaning of superhydrophobic nanostructured surfaces above dew point curve for the first time, which extends applications of superhydrophobic nanostructured materials in low humidity, and is expected to solve self-cleaning problems of outdoor objects in low humidity areas (< 5.0 g•kg −1 ).
