Abstract

In recent years, passive radiative cooling has garnered considerable attention as a sustainable thermal regulation without relying on external energy sources, thus mitigating pollutants generation. However, an intrinsic limitation of these cooling systems lies in the reflective glare, often characterized by an ivory or silvery appearance. This drawback limits their practical application, especially where both functional efficiency and aesthetic appeal are pivotal. Herein, a biomimetic approach inspired by Saharan silver ants' thermoregulatory capabilities is adopted. These ants, equipped with distinctive triangular‐shaped hair, maintain body temperature lower than the ambient air. Leveraging insights from this natural model, a reusable silicon template is employed to fabricate a metasurface structural colored film with a triangular prism array structure using thermoplastic polyurethane (TPU) and the phase separation technique. The film demonstrates an average emissivity of 96% within the atmospheric window and an average solar reflectivity of 93%, leading to a maximum temperature reduction of 8.6 °C during daytime and 5.9 °C at night. Furthermore, the film displays stretchability and mechanical resilience, bolstered by the microscale prismatic structure enhancing superhydrophobicity. This work introduces a biomimetic strategy aimed at augmenting thermal emission while reconciling the challenge of achieving visual appealand high radiative cooling performance.

Abstract

Chang’E lunar microwave sounder (CELMS) data have great significance for studying the lunar surface’s thermophysical features and internal structure. In this study, an area centered at Glushko crater (8.4°N, 77.6°W), one of the typical Copernican craters on the Moon, is selected as the study area. Its microwave thermal emission (MTE) features were investigated with the CE-2 CELMS data. The main results are as follows. First, the Glushko crater is revealed as a cold spot for the first time due to its special brightness temperature ($T_{B}$) performance. Second, the correlation analysis shows that the high rock abundance (RA) plays the most important role in the $T_{B}$ performance observed at the Glushko crater. Moreover, other factors, such as the ilmenite and the surface topography, contribute to the $T_{B}$ distribution to a certain degree, but they do not possess a decisive influence. Furthermore, the spatial difference of $T_{B}$ of the Glushko crater floor reveals that lunar rocks are probably less abundant in the southern and western parts of the Glushko crater.
