Daytime radiative cooling with clear epoxy resin
Solar Energy Materials and Solar Cells, 2020Abstract Radiative cooling (RC) technology without any energy input and any pollution produced has drawn intensive research efforts. However, the high cost and poor performance of RC materials seriously impeded the development of this cooling technology. Here, a facile and cost-effective RC material was proposed to achieve daytime cooling performance.

Green-Manufactured and Recyclable Coatings for Subambient Daytime Radiative Cooling
ACS Applied Materials & Interfaces, 2022Passive daytime radiative cooling, which reflects sunlight and simultaneously emits heat into space to cool surfaces without energy input, is a promising strategy for energy conservation. Integrating radiative cooling with building systems can tremendously alleviate electrical cooling, but manufacturing high-efficient and eco-friendly coatings remains ...

Passive sub-ambient daytime radiative cooling
OSA Advanced Photonics Congress (AP) 2019 (IPR, Networks, NOMA, SPPCom, PVLED), 2019Passive daytime radiative cooling approaches primarily rely on spectrally selective surfaces whose performance is limited by heat gain due to solar absorption and parasitic conduction and convection. We propose and experimentally demonstrate a directional approach to perfectly reject direct solar radiation and an optically-selective thermally ...

Water-Based Hydrophobic Paints for Daytime Radiative Cooling
ACS Applied Materials & InterfacesRadiative cooling paints and coatings make for an effective and scalable approach to implementing daytime cooling. However, paints often contain volatile organic compounds (VOCs), which pose health hazards and harm the environment. Therefore, the negative effects of VOCs must be resolved to ensure full implementation of paints as a radiative cooling ...
