Cascaded Heteroporous Nanocomposites for Thermo‐Adaptive Passive Radiation Cooling

. In such HENFs, theoretical analyses have confirmed the spectrum management superiority of the heteroporous unit in terms of the scattering efficiency strength, with their cascading effect enhancing the overall film-cooling efficiency. The high mechanical performance, phase-transition features, and environmental adaptive properties of HENFs are also exhibited. Importantly, HENFs synergistically couple thermal dissipation and absorption to effectively process heat accumulation and counteract thermal shock in heating devices. It is anticipated that thermo-adaptive HENFs will act as a promising platform for device surface thermal regulation over a wide temperature range.
