Subambient daytime radiative cooling textile based on nanoprocessed silk

Nature Nanotechnology, 2021
Decreasing energy consumption is critical to sustainable development. Because temperature regulation for human comfort consumes vast amounts of energy, substantial research efforts are currently directed towards developing passive personal thermal management techniques that cool the human body without any energy consumption1-9. Although various cooling

Daytime radiative cooling with clear epoxy resin

Solar Energy Materials and Solar Cells, 2020
Abstract 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.

Subambient daytime radiative cooling of vertical surfaces

Science
Subambient daytime radiative cooling enables temperatures to passively reach below ambient temperature, even under direct sunlight, by emitting thermal radiation toward outer space. This technology holds promise for numerous exciting applications. However, previous demonstrations of subambient daytime radiative cooling require surfaces that directly ...

4A zeolite based daytime passive radiative cooling material

Infrared Physics & Technology, 2020
Abstract Materials used for radiative cooling usually have high spectral reflectivity in the solar radiation band (0.3–2.5 µm) and high spectral absorptivity (or emissivity) in the infrared band (2.5–25 µm), particularly in the atmospheric window (8–14 µm). In this work, 4A zeolite was first used as a functional material for radiative cooling.

Water-Based Hydrophobic Paints for Daytime Radiative Cooling

ACS Applied Materials & Interfaces
Radiative 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 ...
