Abstract

Maintaining optimal temperatures continuously is crucial for various applications, yet existing methods relying on selective solar absorbers fail to provide continuous warmth throughout the entire day. A photon-engineered flexible film is proposed for all-day radiative warming, integrating multiple functional layers to regulate radiation across different spectral bands. This design enhances the heat absorption efficiency of solar and atmospheric energy (α0.3−2.5 µm = 0.95, α5−8 µm = 0.75, α14−16 µm = 0.84) while minimizing outward radiation (ɛ8-14 µm = 0.13). Experimental validation demonstrates superior performance over traditional low-emissivity warming blankets under varying environmental conditions, achieving 9.4 °C higher temperature during the day and 1.4 °C higher at night. Moreover, the film's remarkable warming capability highlights its significant application value in anti-condensation. This underscores its potential as a sustainable and effective thermal management solution for carbon neutrality.
