Photothermal superhydrophobic membrane based on breath figure: Anti-icing and deicing

A Passive-Active Anti/Deicing Coating Integrating Superhydrophobicity, Thermal Insulation, and Photo/Electrothermal Conversion Effects

“…In contrast to the PDMS and AP coatings, the superhydrophobic ACP coating has a rougher micronano structure surface, which can trap a large number of air pockets and decrease the contact area between the water droplets and ACP surface, effectively blocking the conduction path of cold air and prolonging the freezing time from 150 to 860 s. Most importantly, the introduction of a superlow thermal conductivity (0.031 W/(m·K)) EP layer can further block the cooling conduction path and prolong the freezing time to 2140 s, showing a significant improvement in anti-icing performance compared to other coatings. In addition, Figure d presents a comparison between the freezing time of the EP-ACP coating and the other recently reported coatings. ,− Obviously, the EP-ACP coating has the highest passive anti-icing performance.…”

“…The interaction between droplets and wall surfaces serves a fundamental role in a wide range of sectors, such as spray, 1,2 coating, 3,4 self-cleaning, 5,6 and anti-icing. 7,8 The impact process can result in phenomena such as rebounding, splashing, and partial or complete deposition depending on factors such as impact velocity, 9,10 viscosity ratio, 11,12 surface morphology, 13,14 and surface wettability. 15,16 Different outcomes play essential roles in various industrial applications.…”

Water-Borne Photo-Thermal Superhydrophobic Coating for Anti-Icing, Self-Cleaning and Oil–Water Separation

“…Superhydrophobic surfaces with a contact angle (CA water ) and rolling angle (RA water ) of water above 150 • and below 10 • , respectively, have an extremely low contact area at the interface adhesion point between solid and liquid and exhibit impressive effects in self-cleaning and anti-/de-icing [7][8][9][10]. In addition, superhydrophobic surfaces with photo-thermal effects would further delay icing time and reduce the de-icing force compared with a mono-superhydrophobic surface [11]. Thus, it can be inferred that the combination of active and passive anti-icing technologies is a wise decision to enhance anti-/de-icing performance in cold environments.…”
