The potential application value of superhydrophobic surfaces with anti-icing and de-icing properties in aerospace, telecommunications cables, energy and other fields has always been an important research topic. In this paper, a kind of superhydrophobic surface with stable structure, sufficient heat, excellent heat transfer performance and mass production was prepared based on elastic material. In this study, the multi-stage micro-nano rough structure is synthesized by ingenious pressing and mold closing control, and the surface contact angle of the prepared sample can reach 159°. The multi-stage micro-nano rough structure on the surface of the experimental sample can make the water droplets form a large number of cavitation, which can delay the icing of static water droplets. The height difference on both sides of (Un)pressed mesh surface makes the water droplets freeze asymmetrically, so (Un)pressed mesh surface has excellent anti-icing ability. The experimental sample is connected with 24 V direct current, and the average resistivity is 1.403 Ω·cm. The temperature can be raised to about 60 °C in one minute. The prepared sample has stable temperature, good electrical conductivity, sufficient heat generation, excellent heat transfer performance and high anti-icing efficiency. This study expands the design idea of anti-icing of aircraft rotor. [Display omitted] [ABSTRACT FROM AUTHOR]

[Display omitted] • A triple conversion strategy is proposed to construct the anti-icing package of rotor leading edge. • The mechanism of photo-thermal deicing and electro-thermal deicing is revealed. • Dynamic deicing analysis and reliability verification are carried out. • The prepared S-RLES has low ice adhesion and high destructive resistance. Aircraft anti-icing and de-icing, aimed at reducing energy consumption, is a compelling technology that enables a plethora of eco-friendly energy applications to overcome long-standing crisis challenges. In this study, we present a tri-conversion strategy, inspired by superhydrophobicity, photothermal conversion, and electrothermal conversion, to develop an all-weather, high-efficiency, and low-energy rotor leading edge anti-icing and de-icing patch. The experimental samples not only possess stable superhydrophobic photothermal conversion capabilities but also achieve a 610-second delay in droplet icing, a 1-second nitrogen blow for frost, and a low ice adhesion strength of 11.6 KPa. Under one sun illumination, it can achieve a stable 54-second static melt and 37-second dynamic melt. With a connection to a 24 V DC stabilized power supply, it showcases an excellent 146-second de-icing capability. The synergistic action of multiple barriers enhances the anti-icing and de-icing performance. This work not only provides rational design principles for high-energy consumption de-icing but also offers insights into harnessing the power of nature for photothermal conversion de-icing.

Ice formation is a widespread phenomenon in nature, and superhydrophobic surfaces, due to their excellent hydrophobic properties, are extensively employed in the field of ice prevention. In this study, silane coupling agent (Si69) is used to modify the petal-like SiO 2 surface to reduce its surface energy. An epoxy/benzoxazine/Si69-SiO 2 ternary mixed superhydrophobic surface is constructed on basalt fiber fabric using a spray and thermal curing method. Examination of the data reveals that a 1:2 proportion of Si69-SiO 2 and epoxy/benzoxazine yields a surface whose hydrophobicity is quantified by a water contact angle measuring 165±2°. The water droplet bounces three times on the surface, demonstrating optimal superhydrophobicity. Compared to samples without the addition of Si69-SiO 2 , the icing time is extended by approximately 4.83 times. Following 30 iterations of freeze-thaw processes, the surface retains its exceptional water-repellent properties, demonstrating excellent ice-phobic stability. Furthermore, the surface maintains its superhydrophobic performance, demonstrating excellent mechanical durability, even after being subjected to friction with SiC sandpaper (220 mesh) for 200 cm under a pressure of 3.2 Kpa and reciprocal friction for 30 minutes under a 50 g load. The surface can withstand over 12 hours of acid and alkali corrosion, and it also possesses excellent self-cleaning capabilities. [Display omitted] [ABSTRACT FROM AUTHOR]
