Title: | Solar-assisted icephobicity down to −60°C with superhydrophobic selective surfaces | Authors: | Ma, W Li, Y Chao, CYH Tso, CY Huang, B Li, W Yao, S |
Issue Date: | 24-Mar-2021 | Source: | Cell reports physical science, 24 Mar. 2021, v. 2, no. 3, 100384 | Abstract: | Engineering icephobic surfaces has been a long-standing effort to address the challenges of ice prevention and removal in our daily life and industrial applications. Superhydrophobic surfaces and photothermal effect have shown their distinct merits in anti-icing and deicing. It is highly desirable to exploit their mutual benefits to realize passive, durable, and sustainable icephobicity even at extremely low temperatures. We report on a superhydrophobic selective surface constructed with a hierarchical architecture to enable stable superhydrophobicity and high-efficiency solar-thermal conversion. The surface spectral selectivity is deliberately designed to maximize solar harvesting while minimizing the thermal re-radiation loss. The boosted solar-thermal conversion empowers remarkable anti-icing of a sessile droplet at a record-low temperature of −60°C under 1-sun illumination. The synergy of solar-thermal conversion and superhydrophobicity endows the surface with superior and durable icephobicity. Moreover, the presented icephobic surface shows great potential and broad impacts, owing to its all-solution-based scalable fabrication method. | Keywords: | Anti-icing Deicing Icephobic Scalable Selective absorber Solar-thermal Solution process Superhydrophobic |
