Bilayer-Structured Passive Radiative Cooling Coating with Thin Thickness, Highly Scattering, and Enhanced Thermal Dissipation

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Май 9, 2025

Passive daytime radiative cooling (PDRC) is a new thermal management solution that does not rely on external energy sources. Traditional PDRC materials have relatively high thickness (typically 500-800 μm), which prevents efficient and limits their application scenarios. To address this challenge, we propose bilayer porous structure meets the needs of different scenarios (both below-ambient above-ambient temperatures). This formed through synergistic assembly inorganic dielectric particles using natural sedimentation phase separation techniques, addressing conflict between performance material thickness. Due to structure, coatings exhibit sufficient solar reflectance (98.59 ± 0.71%), atmospheric emissivity (95.15 0.53%), conductivity (1.203 W·m-1·K-1) with only 220 15 μm. Field tests demonstrate 4.25 °C 15.67 under intense radiation, while coating exhibits impressive durability efficiency. work provides novel construction strategy, showing great potential advance energy-free toward real-world applications.

3D Printing of a Durable Superhydrophobic Film for Daytime Radiative Passive Cooling and Water Harvesting

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Май 12, 2025

Superhydrophobic passive cooling materials offer a promising solution to reduce energy consumption during extremely hot days due their self-cleaning properties, which prevent dust contamination and extend lifetime. However, achieving comprehensive performance, including mechanical durability, resistance strong acid/alkali corrosion, thermal stability, UV radiation tolerance, remains significant challenge. Herein, durable superhydrophobic film exhibiting remarkable superhydrophobicity against the above conditions for daytime water harvesting was prepared based on UV-cure 3D printing postpainting modification. The obtained showed outstanding properties even after being immersed in aqueous solutions with pH values of 2-12 24 h. Compared ambient air, results demonstrated that achieved maximum temperature reduction approximately 21 °C, successfully reduced roof wooden house model. Additionally, exhibited capabilities collection rate 2018.5 ± 84.9 mg cm-2 h-1. Overall, this work not only introduces straightforward method prepare films but also offers innovative addressing scarcity challenges.
