Passive daytime radiative cooling (PDRC) is a sustainable technology that reduces temperature by utilizing materials with high solar reflectance and thermal emittance to provide without electricity. However, its performance often compromised dust environmental contamination, even minimal deposition (0.1 mg/cm2) reducing capacity ∼7.1 W/m2. To overcome this, superhydrophobicity has been integrated into PDRC systems through various techniques materials. This Review explores superhydrophobic (SH-PDRC) systems, examining their principles, preparation strategies, material innovations. Advanced fabrication methods, including electrohydrodynamics, phase separation, chemical vapor deposition, layered patterns, have enabled the development of hierarchical structures optimize reflectance, infrared emissivity, water repellency. A variety polymeric, inorganic, hybrid used achieve durability, stability, resilience. These are tailored enhance for long-term use in extreme conditions, ensuring efficiency. SH-PDRC potential applications wearable textiles, agricultural greenhouses, food preservation, demonstrating versatility. By summarizing recent progress challenges, this aims researchers clear guidelines fabricating advanced enhanced performance, efficiency, paving way designing future cooling.

Radiative cooling technology has major benefits for energy-free thermoregulation since it can chill items without using any energy. However, the efficacy of radiative materials is hampered by outdoor pollution as well a number safety issues involved in practical applications, particular, fire hazard polymer-based materials. Here, porous composite film was created and manufactured that flame-retardant, cooling, superhydrophobic. The average infrared emissivity reached 97.2% with an solar reflectance up to 98.4%. It produced subambient environment, temperature decrease 11.5 °C. With sliding angle 3.6° water contact 158.7°, surface exhibits conventional self-cleaning properties Notably, flame-retardant limiting oxygen index 38.3%, which suitable requirements.
