Dual-Mode Integrated Janus Films with Highly Efficient NaH₂ PO₂ -Enhanced Infrared Radiative Cooling and Solar Heating for Year-Round Thermal Management.

ABSTRACT: The currently available materials cannot meet the requirements of human thermal comfort against the hot and cold seasonal temperature fluctuations. In this study, a dual-mode Janus film with a bonded interface to gain dual-mode functions of both highly efficient radiative cooling and solar heating for year-round thermal management is designed and prepared. The cooling side is achieved by embedding NaH₂ PO₂ particles with high infrared radiation (IR) emittance into a porous polymethyl methacrylate (PMMA) film during pore formation process, which is reported for the first time to the knowledge. A synergistic enhancement of NaH₂ PO₂ and 3D porous structure leads to efficient radiant cooling with high solar reflectance (R̅_solar ≈ 92.6%) an
