Hydrogel-Based Stimuli-Responsive Radiative and/or Evaporative Cooling Materials for Carbon Neutrality

ACS Energy Letters, Journal Year: 2024, Volume and Issue: 9(2), P. 594 - 626

Published: Jan. 29, 2024

Radiative cooling cools by radiating heat toward outer space. Evaporative dispatching the latent of water via evaporation. These two types operate without additional pollutant generation. Hydrogel is one substance that can combine above strategies and thus holds high promise to facilitate construction a carbon neutral society. This review article first documents basic principles related passive cooling, evaporative transfer, light modulation. Then, general considerations for hydrogel-based materials are summarized. Third, stimuli-responsive systems systematically discussed from aspects operation mechanisms as well material selections. Lastly, typical applications radiative and/or in buildings, electronic devices, wearable devices discussed. Challenges further development ending remarks.

Highly Potent Transparent Passive Cooling Coating via Microphase-Separated Hydrogel Combining Radiative and Evaporative Cooling

Nano Letters, Journal Year: 2024, Volume and Issue: 24(23), P. 7055 - 7062

Published: May 29, 2024

Transparent passive cooling materials can cool targets environmentally without interfering with light transmission or visual information reception. They play a prominent role in solar cells and flexible display cooling. However, achieving potent transparent remains challenging, because is accompanied by thermal energy. Here we propose to realize effective via microscale phase separation hydrogel film. The poly(N-isopropylacrylamide-co-acrylamide) presents transmittance of >96% infrared emissivity as high 95%. microphase-separated structure affords higher enthalpy evaporation. film highly adhesive. In field applications, it reduces temperatures 9.14 °C compared those uncovered photovoltaic panels 7.68 for bare light-emitting diode screens. Simulations indicate that energy savings 32.76–51.65 MJ m–2 year–1 be achieved typical tropical monsoon climates temperate continental climates. We expect this work contribute energy-efficient carbon-neutral society.
